A sealing cover is opened, a coolant is injected into a first joint to the interiors of the copperpipe, a water pump is started by the controller to start to work, the water pump extracts the coolant in the copper pipe through an extracting pipe, the coolant is discharged back to the copper pipethrough a discharging pipe, water-cooling is carried out in a circulating mode, the heat-conducting property of the heating furnace for finishing of the steel is better, the waste heat can be eliminated rapidly and efficiently, the efficiency is high, the effect is good, and the problems that after the work is finished, the waste heat is reserved on the surface of the furnace body and cannot be eliminated rapidly, and potential safety hazard exists are solved.

Description

technical field [0001] The invention relates to the field related to steel processing, in particular to a heating furnace for fine steel. Background technique [0002] Steel is a material of a certain shape, size and performance made of steel ingots, billets or steel through pressure processing. Most steel processing is through pressure processing to cause plastic deformation of the processed steel (billet, ingot, etc.), according to the steel processing Different temperatures can be divided into two types: cold processing and hot processing. When steel is used for fine processing, a special heating furnace is required for heating and melting. In the metallurgical industry, a heating furnace is used to heat materials or workpieces (usually metals) to equipment for rolling to forging temperatures (industrial furnaces). [0003] However, there are the following problems in the existing heating furnace for fine steel: [0004] 1. In the existing heating furnace for fine steel...

Problems solved by technology

[0010] The invention provides a heating furnace for fine steel materials through improvement. After the work is completed, it is necessary to quickly eliminate the residual heat on the surface and inside of the furnace body to prevent potential safety hazards. The hot air is discharged. The bottom of the fan is provided with a fixing piece, and the upper end of the fixing piece is provided with fins, which can cooperate with the fan for efficient heat conduction. The bottom of the fins is equipped with a copper tube. Open the sealing cover and inject coolant into the first connector. into the copper pipe, and then the controller starts the water pump to start working. The water pump extracts the coolant in the copper pipe through the extraction pipe, and then discharges it back to the copper pipe through the discharge pipe, and circulates water cooling to make it have better thermal conductivity. It can quickly and efficiently remove waste heat, with high efficiency and good effect. It solves the problem that after the work is completed, there is waste heat on the surface of the furnace body, which cannot be quickly eliminated, and there are potential safety hazards. When the gas pipe is inserted into the gas port, it needs to be removed. To fix, put the gas pipe on the second concave part at the top of the base, the top of the second concave part is provided with an aluminum sheet, which can conduct heat to the gas pipe, and then press down the pressure block on the top, so that the first concave part is fixed on the top of the gas pipe , and then turn the inserting rods at the left and right ends of the top plate to insert them into the socket for fixing. The fixing is fast and convenient, and the stability is good, and it can be applied to most sizes of gas pipes, which solves the complicated way of fixing the inserted gas pipes. The installation is difficult and the fixation is poor. When it is necessary to clean the inside of the furnace body, start the first motor on the top of the fixing seat, and the first motor can drive the blades in the fan to rotate efficiently. The top of the fan can be connected to the The dust in the furnace is efficiently extracted from the tube to the dust collection hood, and then discharged from the air outlet, and discharged into the dust filter. The dust filter is equipped with an activated carbon filter and a HEPA filter to filter the dust efficiently and prevent In the dust filter box, the first and second screens on the left and right sides can prevent foreign matter from entering the interior, and then the purified air enters from the lower left side of the furnace body, so as to circulate, and open the inspection on the top of the dust filter box The cover can process the internal dust, so as to efficiently and stably extract the dust and flying dust inside the furnace body. It is convenient and does not need to consume manpower and resources. Dust is in the furnace body, which is easy to pollute the air. When the inner crucible needs to be taken out, the door panel is opened by the handle, and then the controller starts the second motor to start working. The output shaft at the front end of the second motor starts to rotate, and the shaft coupling at the front end Drive the screw to rotate, and the screw can rotate at the bottom of the sliding plate to push out the sliding plate. During the pushing process, the sliders at the left and right ends of the top of the fixed frame can fix the sliding plate to prevent it from shaking, and the sliding plate The limit blocks at the left and right ends of the top can fix the crucible, prevent the crucible from shifting, and complete the push-out work, so that the internal crucible can be pushed out quickly and stably without shaking, which is labor-saving and safe, and solves the problem of extremely high temperature after the crucible is heated. Not easy to do stable rollout to crucible, less security issue
