Product Description:

Silicon Carbon ball

At present, the iron and steel metallurgy enterprises usually adopt alloying out of the furnace to adjust the steel composition and use the common recarbonizer to adjust its carbon content. When the molten steel is under peroxy state, since the density of recarbonizer is small, it has poor efficiency of adding carbon. On the other side, it can’t sink into the molten steel and there is little possibility of acting with the molten steel, only can act on the top or on surface, so the recovery rate of carbon is low. Nevertheless, many steel enterprises try to resolve the problem by adding carbon cored wire, which increase the production cost and equipment cost, what’s more, it is much difficult t operate.

We has two production lines, the monthly production capacity is 1000 tons.

Q:The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
gas permeable brick have two types:built-in type and external mounted type. the built-in gas permeable brick and the external mounted gas permeable brick are usually made by fire burning, and small part of bricks are made by the low temperature heat.
Q:For refractory, what is critical particle size? Thank you.
For example, in refractory technology, if there is an express of equal to or lower than 0.008mm, 0.008 refers to critical particle size. The main criterion for judging performance of three major continuous casting is the major three normal temperature indexes (compressive strength and anti bending strength at normal temperature, apparent porosity and bulk density). Does this criterion have any defect? How to do multiple test if high-temperature index introduced? Carbon bond is one of the three major castings. How does it form? What do you think of it? Hope someone explains it for me. Thanks a lot!
Q:Who knows about the B-level fireproof insulation materials?
Commonly used B-level materials: Molding polystyrene foam, extruded polystyrene board, gelatine powder polyphenyl granule heat insulating slurry. Although the polyurethane is not the commonly used material, but the 9mm composite of monolayer gypsum board and PU insulating material can reach B-level.
Q:What are the new refractories?
Sintering zirconite. I produce the refractory in Zibo.
Q:Who knows what fire heat preservation material are there?
1 thermal insulation materials with class A combustion performance Rock wool, glass wool, foam glass, ceramic foam, foamed cement, perlite and other 2. thermal insulation materials with B1 combustion performance Specially processed extruded polystyrene board (XPS) / specially processed polyurethane (PU), phenol, powder polystyrene particles. Heat-insulating material with B2 termal insulation performance Fire resistance can be thoroughly sloved by combining molded expanded polystyrene (EPS), extruded polystyrene (XPS) and polyurethane (PU), polyethylene (PE) Hairong module with glass beads (and cooperating with vitrified micro bead inventor Liu Weihua), hope my answer will help!
Q:which kind of material is chosen for fireproofing window?
(1) the inside filler material of steel, wood frame should use incombustible material. (2) window frame uses steel frame or wooden frame with certain strength that can safeguard the integrity and stability of the components. (3) steel frame and mound layer can choose galvanized steel sheet or stainless steel plate. Its selection criteria conform to the article 5.1 in GB12955 Steel Fireproof Door General Technical Condition. (4) the selection criteria of wooden frame and mound layer should conform to the article 5.1 in GB12955 Wooden Fireproof Door General Technical Condition. (5) fire-resistant glass can choose test approved products without affecting the fire resistance of fireproofing windows . Light transmittance of glass should not be less than 75% of same layers commom sheet glass. (6) the sealing material between the frame and the fire-resistant glass should use flame retardant materials, it can play a role of fireproofing and smoke insulation in the fire. (7) hardware accessories should be tested qualified approved supporting product.
Q:How is the division of the fire resistant level of the rock wool board?
It's like this: China's national standard GB8624-97 divides the combustion performance of building materials into the following grades. Level A: non-flammable building materials. Level B1: flame-retardant building materials. Level B2: combustible building materials. Level B3 flammable building materials. section II Combustion performance and fire endurance of building components. First, The combustion performance of buildings of building components. The building is composed of components, such as foundation, walls, lubrication columns, beams, plates, roofs and stairs, ect. Building components are constituted by the building materials, whose combustion performance depends on the combustion properties of the used construction materials. Section One Combustion performance of building components. The building components are divided into three categories according to their combustion properties. First, non-combustible component: the component made by incombustible materials. The incombustible material refers to that when meeting the Oxygen in the air, it will not burn.
Q:Can anyone tell me what is a high alumina refractory?
Refractories refer to a class of inorganic non-metallic materials whose refractoriness are no less than 1580 ℃. Refractoriness is the Celsius temperature when cone-shaped samples can resist high temperature without softening and melting down in the absence of a load. But it is not accurate to define refractory merely by judging that whether the refractoriness is no less than 1580 ℃. Currently, the materials whose physical and chemical properties allow them to be used in high temperature environments are called refractories. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, power and so on, among which the metallurgical industry is the largest demander in this regard, accounting for 50% to 60% of total output. Hope it will help you out!
Q:What are the fire resistances of grc partition panels?
It's ok, calcium silicate itself is a non-combustible material. Light partition walls with keels has the longest fire resistance of 4 hours according to the thickness of the walls. We can talk about it in detail.
Q:What is carbon composite refractories? I hope that the answer is in detail.
