A copper tube heating control method A copper tube synchronous spray water cooling cutting device workbench, the bottom end of the workbench is equipped with supporting feet on both sides, and the top left side of the workbench is equipped with a placement plate , A plasma torch is installed on the top of the support plate, a fixed seat is installed on the top of the support, and a nozzle is installed inside the fixed collar, and the nozzle is connected to the water pump through a water guide pipe.
The copper tube is synchronously sprayed with water to cool the cutting process. When the plasma cutting torch is used to cut the copper tube, the fixing bolts are loosened, and the water pump pumps the water stored in the water collection tank into the inside of the water guide pipe. Water is sprayed out through the nozzle to cool down the nozzle of the plasma cutting gun, which ensures the cooling of the nozzle of the plasma cutting gun, avoids the phenomenon of thermal damage of the nozzle of the plasma cutting gun, ensures that the cutting seam of the copper tube is relatively smooth, and improves the work efficiency. s efficiency.
A method for controlling the heating of a slab in a steel rolling heating furnace, the heating control method comprising the following steps: S1, detecting the real-time temperature field of the slab in the heating furnace; S2, controlling the The working parameters of the combustion device at the furnace position of the slab. At the same time, a steel rolling heating furnace slab heating control system for heating according to the above-mentioned heating control method is also disclosed. Through the above-mentioned technical scheme, according to the real-time temperature field control of the slab The combustion parameters of the combustion device for heating the slab, so as to realize the precise heating of the slabs at different furnace entry temperatures, improve the control accuracy of the target temperature of the slab out of the furnace, and reduce energy consumption and oxidation loss at the same time. The bending process of thin-walled copper tubes in ice equipment, after analyzing the stress and strain in the bending process and the causes of various quality problems, has formulated annealing, lubrication, and copper tube bending processes. Design according to the deformation characteristics of materials The pipe bending die was developed, and the anti-deformation groove and pipe bending mandrel were used to solve the defects of wrinkling of the inner edge and flattening of the outer edge during the bending process. The production practice has proved that the process design is reasonable, the mold structure is simple and practical, and the processed products Good quality, suitable for small batch production. A submerged arc welding wire for ultra-high strength pipeline steel and its preparation method. The technical scheme is: the components of the submerged arc welding wire are: C is 0.040.06wt%, Mn is 1.402 .00wt%, Mo is 0.701.10wt%, Ni is 2.002.60wt%, Cr is 0.801.20wt%, Cu is 0.100.30wt%, B≤0.0005wt%, S≤0.01wt%, P≤0.01wt%, The balance is Fe and unavoidable impurities; the preparation process is as follows: add 0.010.5wt% composite additives in the smelting according to the above components, cast into billets, hot-roll into Φ5.5Φ7.5mm wire rods, and remove surface scale , drawn into a Φ3.2Φ4.0mm welding wire, copper-plated. The composite additive is added in the form of a cored wire. The welding wire prepared in the present invention is matched with the SJ105 flux for welding, and the tensile strength of the weld metal is σ≥910MPa; the weld metal- 30°C impact toughness A≥84J, suitable for submerged arc welding of t2 copper tubes.
