Description
Technical Field
The utility model relates to the technical field of wind power bearing heat treatment equipment, in particular to a heat treatment furnace bottom cushion block for a wind power bearing.
Background
After the rolling of the wind power bearing ring forge piece is finished, quenching and tempering heat treatment needs to be carried out to improve the mechanical property and the service capacity of the ring piece. At present, the bottom block of the internal heat treatment furnace in the industry is basically composed of cast steel and heat-resistant stainless steel. The cast steel sizing block has obvious cost advantage compared with heat-resistant stainless steel, but the cast steel sizing block has serious deterioration and burning loss under high temperature for a long time, so that the bearing product has poor flatness and even is scrapped, and each large ring forging factory has to increase the product allowance to improve the product quality, and the cost is increased greatly. The heat-resistant stainless steel has excellent burning loss performance, obvious product quality advantage and higher cost. The existing heat treatment measures adopt the two sizing blocks, steel plates are placed at the bottoms of the sizing blocks in the actual production leveling process, the steel plates at the bottoms of the sizing blocks are unevenly placed to cause uneven bearing stress, the bottom of a heat treatment furnace is mostly refractory bricks which are extremely easy to break, and the repair cycle is long, so that the product delivery period is seriously influenced, and certain defects are caused. To this end, we propose a heat-treated bottom block for a wind power bearing.
