Abstract

The invention relates to an anchoring piece for a hearth, in particular to a combination anchoring piece with an armor resistant to thermal stress. A hollow hole is formed in a fixed bolt, and the fixed bolt is fixedly mounted on a furnace wall shell. A connecting piece is in an S-shaped bending structure, one end of the connecting piece is connected with a bolt, and the other end of the connecting piece is connected with a horn made of ceramics. The bolt is inserted into the hole of the fixed bolt, and the horn is in a hollow structure. The smaller head of the horn is connected with the connecting piece, and a step is arranged on the outer wall of the larger head of the horn. According to the combination anchoring piece, the bolt and the connecting piece are made of heat-resistant stainless steel materials, the bolt is inserted into the hole of the fixed bolt and can rotate, and the free expansion of a furnace wall is facilitated; the connecting piece is in the S-shaped bending structure, so that the stress caused by thermal expansion and cold contraction of the furnace wall is effectively neutralized; the horn is made of the ceramics, the thermal expansion and cold contraction of the horn are relatively little, and the corrosion resistance is good; the horn shape can keep the tensile force to the furnace wall, and the stability of the furnace wall is improved.

Description

technical field [0001] The invention relates to an anchoring piece for a furnace, in particular to a solid-armor thermal stress-resistant combined anchoring piece. Background technique [0002] Commonly used anchors are made of metal materials, and the castables are fixed on the furnace wall through the anchors; the anchors expand with heat and contract with cold, and are not resistant to corrosion, which may easily cause the castables to fall off. Contents of the invention [0003] In view of the above technical problems, the present invention provides an anchor that is not easily deformed by heat, and the specific technical solution is: [0004] The solid-armor thermal stress-resistant combination anchor piece includes a cylindrical structure of fixing bolts, bolts, connectors and horns. The fixing bolts are hollow holes, and the fixing bolts are fixedly installed on the furnace wall shell. The connectors It is an S-shaped bending structure. One end of the connecting pi...
