The production process
Chrome corundum brick with high purity alumina industry and high purity chromium oxide as raw materials. According to the proportion of design accurately weighing, ingredients, fine grinding and mixing, add a certain amount binder, mixing uniform pressure into waste billet. After waste billet drying, using fused or calcined made from chrome corundum. Chrome corundum by crushing and screening, part of the ground into a fine powder. According to optimal gradation, the fine powder and granular material carry on ingredients, add a certain amount binder, after fully mixing, with friction brick molding machine or hydraulic pressure brick machine molding. After green body dry, at 1800
uniform surface and the inner organization, low porosity, high strength, high wear-resisting performance is good.
2. Good thermal shock resistance. Although due to often open the oven door temperature changes frequently, ut in the steel tapping spout brick has not seen a cracking phenomenon.
3. When repairing the furnace, parts of products can still turn to use, can reduce maintenance costs.
4. The steel tapping spout brick is not casting riser, overall dimension is precise, after laying out the steel tank surface level off, and the construction can be processed according to need.
