Furnace inner base plate for natural gas heating furnace

Abstract

The invention discloses a furnace inner base plate for a natural gas heating furnace. The furnace inner base plate comprises a base plate body made of gray cast iron, the base plate body is provided with a lower surface matched with a bottom surface of a hearth, the base plate body sequentially comprises a plane heating area and a downhill discharging area from a feeding port to a discharging port, the plane heating area corresponds to a preheating section and a heating section inside a furnace body, the downhill discharging area corresponds to a uniform heating section inside the furnace body, the plane heating area is provided with a smooth upper surface, the downhill discharing area is provided with a smooth upper surface which is inclined downwards in the direction from the feeding port to the discharging port, and the base plate body is laid on the bottom surface of the hearth of the heating furnace. The gray cast iron of HT10-26 is selected to be laid on the bottom surface of thehearth built of refractory bricks, the friction between the blank and the bottom surface is reduced, the service life of the hearth is prolonged, meanwhile, the frequency of frequently repairing thehearth is reduced, the repair time and the baking time caused by the fact that the hearth is repaired are avoided, so that the production rhythm is kept.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to an inner backing plate for a natural gas heating furnace. Background technique [0002] In the forging technology, before the forging billet is sent to the forging equipment for forging processing, the forging billet is usually heated. Generally, a hydraulic push rod is used to push the forging billet into a heating furnace such as a natural gas heating furnace or a gas generator for heat treatment. In the existing heating furnace equipment, when the forging billet is pushed and moves in the furnace, friction will be generated with the refractory bricks on the bottom of the furnace. After the forging billet is heated, the friction force will increase, and the service life of the refractory bricks on the bottom will be greatly reduced. In addition, after the refractory bricks are severely worn, the furnace usually needs to be repaired, which takes about 2 to 3 days to complete....

AI Technical Summary

Problems solved by technology

In the existing heating furnace equipment, when the forging billet is pushed and moves in the furnace, friction will be generated with the refractory bricks on the bottom of the furnace, and the friction force will become larger after the forging billet is heated, and the service life of the refractory bricks on the bottom surface will be sharply reduced

In addition, after the refractory bricks are severely worn, the furnace usually needs to be repaired, which takes about 2 to 3 days to complete

After the completion, the furnace needs to be preheated for one day before normal production tasks can be carried out, which will cause continuous production problems
