Atmosphere controlled quenching device for magnetically buffering fall of furnace body

Abstract

The invention discloses an atmosphere controlled quenching device for magnetically buffering fall of a furnace body, and belongs to the technical field of metallurgical equipment. A vertical guide rail is arranged in a case, a guide shoe 11 capable of sliding on the vertical guide rail is arranged on three groups of fixed supporting plates on the vertical guide rail, and a cooling chamber and thefurnace body connected with the cooling chamber are fixed in two cavities formed among the three groups of fixed supporting plates from top to bottom respectively; fixed brackets are arranged at the upper end and the lower end of the cooling chamber; the furnace body and the water-cooled cooling chamber connected together are connected with a traction steel wire of a tractor used for guiding the device to move upwards and arranged at the top of equipment; and a magnet A is arranged at the bottom of the furnace body. A magnet B for generating a repulsive force for retarding free fall of the furnace body and the cooling chamber together with the magnet A is arranged relatively on the same pole as the magnet A at the bottom of the case. By adopting natural fall of the furnace body and the water-cooled cooling chamber and shock absorption stop of the permanent magnets, the atmosphere controlled quenching device has low investment, is easily implemented, and has high quenching speed.

Description

technical field

[0001] The invention relates to an atmosphere control quenching device, which achieves the purpose of quenching through the rapid fall of the furnace body and the water-cooled cooling chamber, and the relative rise of the sample into the water-cooled cooling chamber, and uses a permanent magnet to achieve the stop effect, belonging to the technical field of metallurgical equipment. Background technique

[0002] The quenching process is an important research method in the fields of materials and metallurgy. The traditional quenching method is to cut the hanging wire so that the sample falls away from the high-temperature process. Generally, there is quenching agent water or liquid nitrogen in the lower part. Due to the process of cutting the hanging wire and the action of the quenching agent, such a research method cannot meet the requirements for the atmosphere-sensitive materials. Using a quenching chamber with an atmosphere is a solution to this problem. ...

Embodiment 1

[0024] The present invention provides an atmosphere-controlled quenching device for magnetically buffering the fall of the furnace body, which includes three sets of fixed support plates 10 placed on the vertical guide rail 4 through guide shoes 11, and the three sets of fixed support plates 10 are respectively fixed A body of furnace 18 and the cooling chamber 12 connected thereto are provided. And in order to make the relative position of cooling chamber and body of heater move up and down on track fixed and sealing connection, add fixed support 13 at the upper and lower ends of cooling chamber 12 deliberately. The body of furnace 18 and the water-cooled cooling chamber 12 can move up and down, and its integral upward movement is completed by the traction machine 1 placed on the top 2 of the cabinet through the traction steel wire 6 . Since the traction machine 1 needs to bear a relatively large weight, the outer wall 3 of the chassis carrying the top 2 of the chassis needs ...

[0037] In the following, the application of the invention will be further described in conjunction with the determination of the distribution balance of vanadium in slag and metallic copper.

[0038] First body of heater 18 and water-cooled cooling chamber 12 are lowered to the lowest position as attached figure 2 location shown. The three-stage cooling chamber 12 is opened. The Mo test crucible 16 loaded in the metal Mo hanging basket 15 and the sample high-purity metal copper sheet heated with the furnace and the oxide 17 mixed and pressed in the proportion of slag. The cooling chamber 12 is then installed. The vanadium oxide that needs to be fed at high temperature is compressed into a tablet and loaded into the sampler 7 . Start traction machine 1, body of heater 18 and water-cooled cooling chamber 12 are risen to highest position as attached figure 1 shown. Hanging basket 15, crucible 16 and the sample 17 that heats up with furnace are just in time in the isothermal...
