This invention provides a high-frequency pulsed argon arc welding root welding process for bimetallic composite pipes. The root welding process includes a suitable inner cladding thinning bevel design, welding process parameters, and a high-frequency pulsed arc control method. This invention not only ensures good mechanical properties, appearance, and corrosion resistance at the root of the bimetallic composite pipe, but also allows for a slower heating rate at the pipe end and a shorter cooling time during welding, thereby significantly improving welding efficiency.

This utility model relates to a temperature control system based on cryogenic hydrogenation technology, comprising a stabilization tower, a cooler, and a stripping tower. The cooler includes a cooling box, heat exchange straight pipes, heat exchange coils, and a temperature control component. The heat exchange straight pipe sections and heat exchange coil sections are fixed inside the cooling box. The temperature control component is used to cool the heat exchange medium in the cooling box. The output end of the stabilization tower is connected to a first main pipe, and the input end of the stripping tower is connected to a second main pipe. The input end of the heat exchange straight pipe is connected to the first main pipe via a first branch pipe, and the output end of the heat exchange straight pipe is connected to the second main pipe via a second branch pipe. The input end of the heat exchange coil is connected to the first main pipe via a third branch pipe, and the output end of the heat exchange coil is connected to the second main pipe via a fourth branch pipe. This utility model improves the regulation effect and accuracy of hydrogenated oil cooling, reduces cooling medium consumption, and saves resources.

The utility model relates to a kind of heating cooling pot, comprising: pot body, heating box and cooling box, the first opening is formed in the pot body upper, the pot body outside respectively with heating box and cooling box contact and fixed connection, the height of cooling box is higher than the height of heating box.The utility model is provided with heating box and cooling box outside pot body, food after stewing does not leave pot body, directly cools in pot body, reduces the temperature of food after taking out, and makes food more into flavor;Food lower taking-out temperature, food is short in outside cooling time, accelerates the production efficiency of production line, food turnover is faster, so that the required cooling area is smaller;Cooling box and heating box are arranged up and down, by the convection of material soup, so that the temperature of material soup in pot body is more average, so that the consistency of food after stewing is good.
