We make graphite parts from top grade graphite material. The finish part has excellent mechanical property. With the high compressive strenggh and high thermal shock and corrosion resistance,the usage loss is very low. It can save both your time and money.

Q:How is the division of the fire resistant level of the rock wool board?: The fire rating of European style rock wool board is level A , which uses Da Guang Beijing Jinyu rock wool board, with the main advantages are: 1, High acidity coefficient: The high coefficient of acidity greatly improves the life resistance and weather resistance of the rock wool board. 2, Hydrophobic air permeability: According to the picture, Jinyu Star rock wool is water-repellent, at the same time it also has breathability, so the liquid water is not easy to dip into the rock wool, and the water vapor and other gas molecules could pass through the rock wool. In particular, the insulation materials have this feature which enables the building to have "respiratory function" thus making the room more comfortable and preventing anti-mildew phenomenon happening indoor. 3, Environmental protection: The goldfish can survive freely, which just shows it is environmental; 4, High strength: The advanced pleating and curing technology make the rock wool board tensile and high compressive strength. It not only can be applied on the external wall thermal insulation and sandwich board core material, but also can be used to make structural cotton in the flexible waterproof roofing. Its quality is so stable that it is convenient in construction and durable in use. 5, Fireproofing: Not just talking about the fire rating, but the fireproofing time, which is generally up to two hours, and can be used for lining thermal insulation fire-resistant part of the glass curtain wall, through-wall pipe seal, pier?between?two?windows, window sill wall and other parts; 6, Derived advantages: Agriculture applies the soilless cultivation cotton;

Q:What brands are the best in the A-level refractory materials?: A-level refractory materials: Dulux, Nippon, Carpoly, Skshu and Smoz. Fireproof boards are the most common materials in the market. There are two are commonly used: one is HPL decorative plastic laminates with advantages of fire- ,moisture-, wearproof and oil resistance as well as easy to wash, besides it has a great variety of colors and types. Another one is glass fiber magnesite fireproof board, the out layer of which is decorative materials while the inner layer is mineral magnesium fireproof materials which can resist a high temperature of 1,500 Celsius degree but it is not a good ornament.

Q:Where is the production of refractory manganese alloy manufacturers? Manganese is recommended between 63 and 70!: The cut is relatively transparent if you jam, we have also used silicon manganese alloy

Q:Refractory materials are needed for casting metallurgy.: Refractory material used in foundry work is that refractories for cupola furnace? Cupola is a high temperature furnace which is used for melting molten iron, and refractory material adopted is mainly low iron high grade clay brick and clay lightweight insulation bricks, etc.foundry ingot refractory material is pearl sand (also known as pearl jewelry sand, fused ceramic, ceramic sand) it is made of high quality bauxite material by arc melting furnace.

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:What is refractory?: Refractory is an inorganic nonmetallic material with minimum refractoriness of 1580 ℃. Now, refractory is not defined merely by judging that whether its refractoriness is at above 1580 ℃. Currently, refractory, an inorganic nonmetallic material, are widely used in metallurgy, ceramics, power and other industrial fields.

Q:How to divide the fire resistant level of construction thermal insulation materials?: 1, Combustion performance of the national standard building materials are divided into the following levels: Class A: incombustible building material: Material that almost never burn. Class B1: nonflammable building material: Nonflammable materials have good effect of flame resistance. In case of fire it in the air or at high temperature it is difficult to catch fire and spread, and when the fire source is removed, the combustion can stop immediately. Class B2: combustible?building?material: Combustible materials have good effect of flame resistance. In case of open fire in the air or at high temperature, it will immediately burst into flames and spread the fire quickly, such as wooden column, timber roof truss, wooden stairs, etc. Class B3: flammable building material: No flame-retardant effect, highly flammable, high risk of fire. 2, According to fire?rating, external wall thermal insulation materials can be divided into 1) thermal insulation material with class A combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite,etc. 2) thermal insulation material with class B1 combustion performance: Extruded polystyrene board (XPS) after special treatment /polyurethane (PU) after special treatment , phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) thermal insulation material with class B2 combustion performance: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q:What kind of refractories do the anode baking furnace use?: Usually the clay refractory bricks will be able to meet the requirements

Q:How long usually will the A-level fireproof materials prevent the flame?: The classification of A-level materials is based on GB8624 - 2006 building materials and products combustion performance of grading method. Specific technical requirements are: 1, temperature ≤30 degrees; mass loss rate ≤50%; continuous burning time is 0; 2, the gross calorific value of main components, overall products, external non-substantial components ≤2.0MJ / kg; any internal non-substantial component ≤1.4MJ / kg;

Q:What are the refractories for converter?: Permanent layer (sintering) magnesia brick, the working lining gunning material for the working layer and the permanent layer gap, using magnesia ramming materials, MgO-C brick brick supply,
