1. The surface of the tempering furnace is 15MM thick and high-aluminum porcelain plate

Shandong heat shield high-alumina porcelain plate is a lightweight and ultra-thin sheet-shaped refractory material. Its main components are AI2O3, SiO2 and other auxiliary materials. All materials are blended according to a predetermined ratio and then beaten and vacuum filtered. The surface of the product is a hard protective layer made of a variety of imported refractory powders. The protective layer is uniformly compounded on the surface of the board by Shandong heat shield technicians through special equipment, and each side of the board has a balanced hardness.

Shandong heat shield high-aluminum porcelain plate has the characteristics of high hardness, low shrinkage, corrosion resistance, long service life, and no powder loss. Good mechanical strength and superior thermal shock resistance make it not powder and deform under the working conditions of rapid cooling and rapid heat and high-temperature air flow. It can be directly used as various thermal equipment (glass tempering furnace, The hot surface lining material of ceramic kiln, etc.).

2. Roller heat preservation block of tempering furnace

The roller insulation brick (roll seal) produced by Shandong Redun High Temperature is made of high-quality aluminum silicate fiber cotton and vacuum formed. Each insulation brick is carved and milled by CNC machine tools, which can maximize the accuracy of the different parts and apertures of the insulation brick. Degrees. The product has the characteristics of low bulk density, light weight, high hardness, good heat preservation effect and long service life. The superior mechanical strength and good thermal shock resistance make it maintain its existing characteristics even when subjected to high temperature airflow. This product has been widely used in many domestic well-known tempered equipment such as North Glass, Fuyao Glass, Saihe Glass, etc. It has a good effect of heat preservation and energy saving, and solves the heat preservation problem that many tempered glass enterprises cannot overcome during the long-term production.


Shandong Redun high temperature roller insulation brick series products are non-standard customized products, and support processing with drawings and samples. In addition to the length, width, and thickness of the insulation brick, the roll diameter, roll spacing and number of ceramic rolls must also be provided.

3. Aluminum silicate backing board/insulation board

This board is used for the middle and outermost layers of the tempering furnace. It is mainly used for heat preservation and does not touch the fire surface. The general thickness is 50MM thick 1260 standard board and 1260 ordinary board.


Shandong heat shield ceramic fiber board is a hard board-mounted refractory insulation material made of high-quality ceramic fiber loose cotton with a small amount of binder, and vacuum forming. It maintains good mechanical strength even after high temperature heating, with 1050°C, 1260 °C, 1350°C, 1430°C, 1600°C, 1700°C. With high strength and good resistance to airflow erosion, it can be directly used as a lining material for hot surfaces.
