Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel plate processing, and particularly relates to a loading and unloading machine for a stainless steel solution furnace. Background Technique

[0002] The solution treatment of 300 series stainless steel is to heat austenitic stainless steel to 1000°C to 1150°C, dissolve all carbides into austenite, and then rapidly cool to obtain a single-phase austenite structure heat treatment process. When the carbon content is on the high side, the upper limit temperature is taken; when the carbon content is on the low side, the lower limit temperature is taken. A chamber solution furnace is an industrial furnace device that can be used for the heat treatment of stainless steel plates. When performing solution treatment on stainless steel plates, by heating the steel plates to 1000°C to 1150°C and holding for a sufficient long time, the carbides of ordinary stainless steel grade 304 are melted into austenite, and then rapidly cooled (water quenched), so that a single-phase austenite structure can be obtained at room temperature. Since the temperature of the stainless steel plate after being treated by the chamber solution furnace is relatively high, a special loading and unloading machine is required to load and unload the stainless steel plate. For the existing loading and unloading machine, during actual use, tracks need to be installed on the ground, and a forklift transports the stainless steel plate through the tracks. At this time, the rear edge of the forklift is 9.2 meters away from the edge of the transmission device, and there are the following technical defects: when the factory building space is small, it is very inconvenient to use, and the space utilization rate is low.

[0003] Medium and thick plates of titanium and titanium alloys have excellent properties such as good corrosion resistance and high specific strength, and are widely used in the fields of aerospace, navigation, metallurgy, chemical engineering, petrochemical industry, etc. After hot rolling in the pressure processing process of medium and thick plates of titanium and titanium alloys, due to the large rebound ability and high strength of titanium and titanium alloy plates, it is usually very difficult to level at room temperature. During the annealing treatment process, the original elastic deformation of the metal material is replaced by creep deformation (most of which is plastic deformation), and the stress of the material is gradually released over time. The leveling of titanium and titanium alloy plates generally adopts a processing technology method that combines leveling and annealing. Among them, the type of heat treatment furnace and the heat treatment furnace equipment technology determine the technical standards reached by the plate shape flatness of titanium and titanium alloy plates, and also determine the uses of titanium and titanium alloy plates. At present, there are mainly two types of heat treatment leveling equipment for medium and thick plates of titanium and titanium alloys used by well-known enterprises at home and abroad: One is the vacuum creep leveling (VCF) furnace. After titanium and titanium alloy plates are processed by the vacuum creep leveling (VCF) furnace, the flatness of the product is ≤2 mm / m (some reach ≤1.5 mm / m), with high precision, meeting the technical standard requirements of aviation plates and industrial plates and satisfying the needs of users. However, the heat treatment cycle of a furnace of titanium plates is 48 - 54 hours. The titanium plates are stacked in the furnace, and there is a heat-resistant felt (composed of vermiculite) on it. The loading and cleaning of vermiculite powder have the following technical defects: large dust, poor working environment. In the area of the titanium plate stack in the furnace, there are stainless steel plates (lower backing plate, upper partition plate) above and below the stack. The stainless steel plates are vacuum creep leveled with the furnace, increasing energy consumption. The other is the car-bottom furnace. The advantage of this equipment is that after titanium and titanium alloy plates are heat-treated by the car-bottom furnace, the flatness of the product is ≤3 mm / m, with relatively high precision, meeting the technical standard requirements of industrial plates and satisfying the needs of users. There are the following technical defects: There is a material rack on the furnace platform. The material rack is made of materials with a high Ni content through casting and processing, with a high cost. During heat treatment, it is creep leveled with the furnace, increasing energy consumption.

[0004] Therefore, how to design a loading and unloading machine for a chamber solid melting furnace that can effectively save space, improve space utilization rate, save energy consumption on the chamber solid melting furnace, and shorten the heat treatment cycle has become an urgent problem to be solved.
