- Q: How much is the bending temperature aluminum silicon carbide brick for torpedo car
- High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
- Q: What are the high aluminum bricks made of?
- The amount of refractory mud accounts for about 6% of the brick weight
- Q: What are the reasons for the spalling of refractory bricks in the production of lime kiln?
- In the course of the production of lime kiln, the local block of refractory brick is a very dangerous signal. It is suggested that you stop the kiln to prevent the collapse of a large area. Lime kiln is the main equipment for the production of limestone kiln and rotary kiln is two, with the growth of calcium carbide lime kiln industry, iron and steel industry, the construction industry to the amount of limestone has become the main production equipment, and refractory bricks became the heart of lime kiln.
- Q: Introduction of high alumina brick
- Three alumina silicate refractory product with a content of two Al2O3 (48%).
- Q: What refractory material does cupola lining use?
- Materials defined as physical and chemical properties that allow them to be used in a high temperature environment are called refractory materials. Refractory materials are widely used in metallurgy, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest amount of metallurgical industry, accounting for 50% ~ 60% of the total output.
- Q: What is the standard size of high alumina brick?
- Standard brick: 230 x 115 x 65; four points: 230 x 115 x 40; three points: 230 x 115 x 30; 150 x 120: Brick gable. Light weight brick 1 to 1.7 kilograms; heavy clay superscript brick weighs 3.75 kilograms; light 30 plates 0.79 kilograms; light 40 plates, 1.05 kilograms.
- Q: How are the high alumina bricks fired?
- Generally, the high alumina bauxite is added with a small amount of clay. After being ground, the gas is injected and shaped in the form of slurry by the way of gas attack or foam, and it is burnt at 1300~1500 DEG C. Sometimes industrial alumina can be used to replace part of bauxite clinker. Used for lining and thermal insulation of masonry kilns, as well as for areas where there is no high temperature, high melting material erosion and erosion effects. When touching the flame directly, the touch temperature shall not be higher than 1350 degrees.
- Q: How does the physicochemical index change when the high alumina brick is used at high temperature?
- When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.
- Q: Which thermal shock stability of clay brick and high alumina brick is good?
- High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.
- Q: The difference between clay bricks and clay bricks
- Clay brick is a small building with artificial bulk. Also called sintered brick. Solid clay brick is one of the oldest building materials in the world. It is a building material that is loved by the people.
