- 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: What is the price of the latest thermal insulation material?
- There are many kinds of insulation materials, and the price will fluctuate with the market. Small quantities of inquiry or procurement, then go directly to the local thermal insulation market, a wide variety of prices are basically the market price.
- 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: What are the specific raw materials for plastic pallets?
