Dry (silk) basic refractories range of applications: · metallurgy, refractory (Refractory material) industry: ultrafine particles neutral refractories is a silicon carbide corundum water cannons mud in one of the main components of the gun mud filled with strong, durable, and fully sintering within 20 minutes, and the required strength, non-mixed hot metal, corrosion resistance and easy in closure easy customization shaped refractory bricks, having consistent with iron conditions durability custom shaped refractory bricks, volume stability, thermal stability and insulation refractoriness physicochemical properties; pug good adhesion, no Peng expansion, fast drying, plasticity, and antiferromagnetic stream erosion and other advantages. · Welding: the neutral refractories is a new custom shaped electrode coating material firebrick, refractory neutral uniform particle size distribution, excluding large particles of foreign matter, in the arc burning blasting does not produce custom shaped firebrick , thus reducing spatter, while reducing the burning of sound production process to solve the welding electrode coating recurring cracking; at the same time has a certain elasticity, slippery plastic, increase in welding and powder coating cylinder fluidity, improve the extrusion coating performance, substitution of titanium dioxide, reducing the electrode cost. Brick shape should meet the requirements of quality brick shape quality should meet the following requirements: (1) size tolerance: height tolerance of soil 2%; wedge face and head width tolerance bulk soil 2mm; the difference between the size of the first soil tolerance 1mm; Length Tolerance ± 1%, but the biggest difference is the soil 2mm. (2) edge damage. Allow hot or cold surfaces damaged two sides reached 40mm long and 5mm deep; but not exceed. (3) Loss angle. Hot and cold surfaces are only allowed to have one corner damage, loss angle at three edges and corners of damage does not exceed the length of 50mm. Does not exceed the loss angle of 20mm. (4) Crack. Tile allows fine hairline cracks; not allow cracks parallel to the bearing surface; no longer than 40mm, no wider than the other crack 0.2mm is allowed. (5) pits, melting tracks and drum kits. Allow pits and a maximum diameter of melting traces of 10mm, the maximum depth of 10mm; bulge maximum 0.5mm. There are a number of bricks of various edges of the brick shall not exceed 70% of the total.
