Characteristics of Using Anchor Bricks for Heating Furnace
Anchor brick, also known as hanger brick. High aluminum anchor brick is an indispensable refractory brick for heating furnaces, coal chemical furnaces, and other thermal kilns, so it is also called steel rolling heating furnace suspended arch brick. Anchor bricks are mainly used for anchoring refractory castables. The properties of anchor bricks should be consistent with the materials of the castables and the expansion and contraction should be consistent, so as to form a close combination with the castables and extend the life of the furnace lining.
Anchor brick is a kind of refractory brick for industrial furnace roof and furnace wall. It is buried in the wall of refractory castable and can be used after baking at a certain high temperature. Its role is to enhance the overall performance of refractory castables.
Due to the field of use, the shape of the high alumina anchor brick is more complicated. In the process of use, it must withstand the effects of high temperature, high pressure, load, hot air flow scouring, atmosphere, periodic cold and hot alternating, and the harsh environmental conditions.
The anchor brick is used as a rib brick for the roof of industrial furnaces. It is a column consisting of hanging ends and anchors. On the surface of the anchor, grooves are distributed at intervals. A rib is provided on at least one surface of the anchor along the length direction. After the ribs are installed, due to the reinforcement and pulling effect of the ribs, the tensile strength and flexural strength of the anchor are significantly improved. The stress generated at the groove is blocked at the ribs and cannot continue to be transmitted, so the anchor brick is not easy to break.
After molding, the refractory castable is hung on the anchor, and the anchor is hung on the steel clip. The steel clip is hung on the steel hook, and the hook is hung on the small I-beam. The small I-beam is supported on the large I-beam. The benefits of this structure are as follows.
① Heat-resistant steel anchors were replaced with refractory anchor bricks. The damage caused by the slow oxidation of heat-resistant steel is avoided, and the service life of the lining is extended.
②Reduce the working temperature of metal parts. Ordinary steel can be used to replace expensive heat-resistant steel to reduce the cost of the kiln.
③ As the length of the anchor bricks is increased, the working temperature of the steel clip at the rear of the anchor is reduced, and the oxidation of the steel clip is avoided. The thickness of the light material covered by the upper part of the refractory castable can be increased, and the heat insulation and energy-saving effect of the kiln lining can be improved.
Many users use hanger bricks with insufficient tensile strength, resulting in a severe imbalance of stress and the collapse of the furnace roof.
