Choose lightweight refractory castables, preferred Goodyear refractory, Goodyear refractory market demand-oriented, and actively learn from the international counterparts of the advanced experience, and generally seek the views of users around the world, carefully developed a variety of energy-saving, high-efficiency, safe, environmentally friendly products have been certified by the prestigious departments. Lightweight refractory castables are used as follows

First of all, the mold and casting contact surface clean, add water in the casting material so that its water content reaches 42-45%, 24 hours after demolding, hanging plastic film natural recuperation 2-3 days after the ignition of the baking furnace, the casting material contains a small amount of combined water and free water, the baking furnace to pay attention to the control of the temperature rise, to avoid the accumulation of sudden temperature rise to form a burst of cracks and flaking, in particular 120 ° C, 350 ° C, 600 ° C, 800 ° C, the temperature rise should be slow. Temperature rise should be slow, to have a certain degree of insulation work. It is recommended that 120 ℃ below not less than 48 hours, 350 ℃ below not less than 96 hours, the current hourly heating 20-30 ℃, until the application temperature.

Kelde abide by the business reputation and reciprocity and mutual benefit principle, dedicated to providing users with the best service, and is willing to work with friends from all walks of life to work together to create prosperity. Layer. At high temperature, chromite FeO reaction desolvation and the formation of secondary spinel, so that the volume of the sintered layer changes and cracks, so that when the slide is opened, the lower part of the water mouth is not sintered diversion sand quickly outflow, sintered layer cracks quickly expand, in the steel static pressure sintered layer under the action of the static pressure is completely destroyed, so as to be able to achieve the purpose of the automatic opening of the pouring. Chromium quality diversion sand is used by most large steel mills, accounting for the whole ladle with diversion sand of 30% or so, especially the refining ladle.
