Black / Green  Silicon  Carbide  prices

Silicon carbon is a new kind of reinforced steel-making deoxidizing agent and ideal thermal insulating agent.it is used for deoxidizing. The usage dose is 1-4kg/t can make electricity consumption to reduce 15-20kw/h and time to reduce 15-20min per furnace to raise productivity rate to 8-10%.

Advantages: 

 

(1) Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities.

 

(2) Good hardness, longer life.

 

(3) Chemical washed and water washed good cleanness.

 

(4) Special treated products get higher purity, better toughness, and better grinding effect.

Q:Are the rubber insulation materials are refractory materials?
Compared with the fireproofing properties, the main thermal insulation properties of level B1 will be carbonized and drop when it is over 200 degree.

Reference: It is provided from technicians of Guangzhou Ou Fu construction materials: The answer that has been got:

Q:Is the linear change on reheating the same as heating permanent linear change of refractory material?
“+”represents expansion. the afterexpansion and aftercontraction after cooled to be at room temperature. The change may significantly damage the masonry of thermal kiln. There are regulations on the linear change on reheating of common refractory material in the national standard. Some physical chemical changes may continue. It is defined as the change from being heated to the specified temperature of refractory material sample. Heat preserving for a while till afte cooling to be at room temperature, then the residual will expand or contract in its length, heat preservation for a while, organization vitrification, the irreversible changes of its length refers to heating the firing refractory to be at high temperature, so as to make the volume of refractory materials expand or contract, due to the influence of uneven temperature or lack of time, otherwise it will cause the deformation of the refractory ball and make this indicator within standard even reach smaller value, so firing control must be strengthened in product production. But it is should not be too high. For refractory materials with same chemical composition, the linear change on reheating is produced in the heating process. Properly increasing sintering temperature and prolonging the holding time is an effective process measures, make its firing inadequate. When subjected to high temperature, it can reduce the thermal shock resistance. Minus sign "-" represents contraction. The permanent line rate refers to heating the fire refractory ball to the specified temperature. Linear change on reheating, also known as residual linear change, is an important indicator to assess the quality of refractory in the long time use. To control the permanent line rate within the standard or reach the minimum value.
Q:Is the ball mill used in production of refractories?
Refractory is a kind of non-metallic material that is of resistance to thermal shock and chemical erosion, low thermal conductivity and low expansion coefficient. The refractoriness of the refractory is not less than 1580℃. The usage of the refractory is broad. Refractory materials include refractory bricks and powders. Abandoned refractory bricks can be recreated as new bricks after they are crushed by a crusher and grinded by a ball mill. The ball mill and crusher are needed to grind and crush the material in the production of the refractory. The ball mill produced by Zhengzhou Xinhai Machinery Manufacturing Co. has excellent performance and there are many successful cases in Inner Mongolia, Heilongjiang and Guangdong. At the request of the national environmental policy, the company adjusts the equipment details, allowing the equipment to ensure the volume of production while reduce energy consumption.
Q:What are the application of old refractory bricks?
It can still be used as refractory bricks or refractory. The quality of auxiliary material is not as good as bauxite.
Q:which is better as household fireproof material ?
the thickness recommended is 1mm or more # 304 stainless steel plate, refractory corrosion-resistant, easy to clean. It now appears that among the most common fireproof material, asbestos is the best. But the asbestos harmful effect is also great, especially for lung damage. Now on the market, the polyurethane, polystyrene, rock wool glass wool, phephenolic aldehyde fireproofingthermal insulation board. But now the phenolic aldehyde fireproofing thermal insulation board has superior performance! phenolic aldehyde containing only carbon, hydrogen and oxygen atoms, when subjected to pyrolysis, except small amounts of CO gas, the other will not produce toxic gases, maximum smoke density is 5.0%.
Q:Does anyone know the characteristics of refractory for glass kiln?
The characteristics of refractory for glass kiln: First, it can well resist the erosion of glass fusant and gas actor, and has sufficiently high load softening temperature and thermal stability. Usually we hope the refractories of all parts of the furnace will has no partial early erosion phenomenon to ensure that the entire furnace has a sufficiently long service life. However, due to the different mechanical, physical and chemical conditions of different parts of glass furnace, the performance of refractories should adapt to the glass furnace thereto and at the same time has no adverse effect on the adjacent other kinds of brick materials. Besides, we should consider the price of brick material, we should try to consider using commonly used stereotypes bricks of standard sizes which is cheap and quickly supplied by the warehouse. The damage of glass melting furnace lining is mainly due to chemical erosion, assisted by thermal stress. The degree and speed of chemical erosion is closely related to the applied parts, furnace temperature and melting glass varieties, and of course, the quality of the lining itself is also crucial. The nature of refractories using in the glass furnace has a very significant impact on the operation of glass melting furnace and the quality of glass. The application of poor main beam refractories will not only cause frequent shutdown for maintenance, limiting melting temperature, lowering furnace output, but also shorten the life of the furnace, and make glass has a variety of defects (stripes, stones, etc.), lower the quality of the glass. Here are the description of the nature and purpose of commonly used refractory in glass furnace.
Q:Is fireclay poisonous?
Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.
Q:Who knows what is the standard of insulation material whose fire proof is level A?
Level A is distinct from B in coefficient of fire proofing. Level A is non combustible, while Level B is divided into B1( flame retardant), B2(combustible) and B3( inflammable). Currently in the market, level A materials are as follows: phenolic, rock wool, insulation mortar, ceramic foam, foam glass, and foamed concrete. The most advantageous of level A material at present is foamed concrete, also known as foamed cement. Xuzhou Lvchuang Construction company is working on this, you can search fro it on the internet, it has high cost performance.
Q:What's the fire endurance of hollow brick?
For hollow brick wall, it should be noted that outside are 200-thick coal gangue hollow brick wall on interior wall. Besides, the fire endurance should comform to GB50067-97 Fireproof code for garage, repair garage, parking lot design. 3), All joints of brick walls and concrete wall column should reserve rebar tie. Masonry mortar in internal and external walls should be full. Wall masonry should be up to bottom of beam slab and filled tightly with 1:3 cement mortar.
Q:What the fireproofing materialare of the refractory kettle and where they can be sold?
Many places sell these. Nearly 10 years, can't brun when it is dry, adsorption. You can also baidu these materials. Heat transfer evenly, feldspar, clay and other raw materials with a ceramic products. Traditional casserole can not resist heat difference and also can withstand for 100 high temperature without crack. Aiming at the problem of traditional casserole, easy to crack and air permeability, people joined the spodumene on raw material, produce a high-temperature resistance casserole. It is produced after the high temperature burning makes an earthenware pot to keep the original advantages. Hebei has many places to sell these materials and is also relatively cheaper. The traditional casserole has features of not easy to transfer heat's quartz and slow cooling. Due to production technology and raw materials, it greatly improves the casserole' practicability after research and improvement.
