Problems solved by technology
The traditional valve pre-forging heating equipment uses kerosene blowtorch to preheat the blank before forging. The heating environment is open heating, the working conditions are harsh, the cost is high, the degree of automation is low, the heat loss is large, the energy utilization rate is extremely low, and the blank The heating temperature fluctuates greatly, and the heating temperature of the blank depends on the operation of the workers to a large extent and is affected by the environment, which greatly affects the quality of the final valve

The invention discloses a constant temperature heating furnace before valve forging, which comprises a furnace, a temperature sensor and a controller. There are a plurality of furnace bricks separated by a certain distance in the furnace, and heating pipes are installed on the furnace bricks. A support plate is installed, and a feed pipe is installed through the middle of the support plate. The bar material enters from the side of the feed pipe, is heated by the heating tube, and is discharged along the lower discharge plate; there are detection holes on the furnace brick. The temperature sensor is installed in the detection hole to detect the temperature inside the furnace in real time. When the temperature inside the furnace reaches the preset temperature, the controller controls the heating tube to maintain the set temperature range. The invention adopts the principle of electric heating, and the heating cost is greatly reduced compared with the traditional mode. Under the action of the temperature sensor, the temperature in the furnace is stable at the set temperature, and is not disturbed by the environment. The bar is gradually heated by the heating tube and then leaves the furnace. The temperature of the discharged bar is stable and uniform.
Description
technical field [0001] The invention relates to a heating furnace, in particular to a constant temperature heating furnace before forging of a valve. Background technique [0002] In the processing process of the valve, the essential process is to use the heating furnace to heat the bar blank before forging. The traditional valve pre-forging heating equipment uses kerosene blowtorch to preheat the blank before forging. The heating environment is open heating, the working conditions are harsh, the cost is high, the degree of automation is low, the heat loss is large, the energy utilization rate is extremely low, and the blank The heating temperature fluctuates greatly, and the heating temperature of the blank depends on the operation of the workers to a large extent and is affected by the environment, which greatly affects the quality of the final valve. Contents of the invention [0003] The purpose of the invention is to solve the current technical problems of constant t...
