Heating furnace with oxygen blowing mechanism for steel casting

Abstract

The invention discloses a heating furnace with oxygen blowing mechanism for steel casting, and belongs to the field of steel casting. The heating furnace with the oxygen blowing mechanism for steel casting comprises a heating furnace main body, a gas control mechanism, a heat collection water tank, an explosion-proof door, a U-shaped water pipe, a combustor, an oxygen generator and the oxygen blowing mechanism. An explosion-proof door is installed outside the heating furnace main body through hinges, a base is fixedly installed at the bottom of the heating furnace main body, the heat collection water tank is fixedly installed on the outer wall of one side of the heating furnace main body, and a water guide pipe is installed between the heating furnace main body and the heat collection water tank. According to the heating furnace with oxygen blowing mechanism for steel casting, by installing the oxygen blowing mechanism, when the oxygen blowing mechanism is subjected to gas pressure, due to uneven stress, the oxygen blowing mechanism can rotate, and in the working process of the oxygen blowing mechanism, oxygen can be rotationally sent out through all oxygen blowing openings of therotating oxygen blowing mechanism, so that the spreading breadth and the distribution range of the oxygen are greatly extended, and the oxygen blowing effect is further improved.

Description

technical field [0001] The invention relates to the field of iron and steel casting, more specifically, to a heating furnace with an oxygen blowing mechanism based on iron and steel casting. Background technique [0002] Iron and steel is a metal material with the metal element iron as the main element. Its general forms include pig iron, steel, steel, ferroalloy, etc. Casting is a metal heating process. Generally speaking, the metal liquid is poured into the parts. In the mold corresponding to the shape, so as to form a good shape body, after the mold is cooled later, a blank or part that is consistent with the shape and size of the part can be obtained. The process is due to its excellent effect and excellent production efficiency. It is widely used in the metal production industry. In the process of iron and steel casting, it needs to be heated, and when it is heated, a heating furnace is needed. [0003] Chinese patent document CN201921928674.2 discloses a heating furna...

Problems solved by technology

The device type adds the first vibration switch, the second vibration switch, camera, mounting plate, hidden normally closed button, high temperature resistant see-through window and buzzer. The safety protection of the heating furnace for beam casting is not good enough, which improves the timeliness of the alarm of the device. The first vibration switch and the second vibration switch have the same specifications, and the first vibration switch and the second vibration switch are tiled inside the original ground. This design It is convenient for the first vibration switch and the second vibration switch to be used together, because there is an installation groove inside the opening and closing door, and the installation groove matches the high temperature resistant see-through window, the high temperature resistant see-through window is connected with the opening and closing door through the installation groove, and the installation groove It is convenient for the installation and use of high-temperature resistant see-through windows, but the device is not equipped with any oxygen blowing mechanism. When heating the parts, it is impossible to add oxygen to the device according to the demand, so that the heating flame in the device cannot be adjusted. , when some metals are heated, they also have high requirements for the amount of oxygen, which will have a certain impact on the final heating body, and there is no heat collection structure installed in the device. When heating steel, Some excess heat will be wasted and cannot be effectively used, resulting in a waste of resources. At the same time, there is no steam generation structure installed in the device. Before a new round of steel heating, some gas will remain in the device, which cannot be obtained. It has a great potential safety hazard and is not safe to use, so it needs to be improved to a certain extent.
