How to cut a torpedo canister? What are torpedo tanks for

Large torpedo tank blanking and assembly welding method.

A large-scale torpedo tank blanking and assembly welding method comprises using computer to calculate the blanking of tank body, tank mouth, numerical control automatic cutting machine for cutting, it is characterized in that it comprises the following steps: 1) Blanking and forming of tank body, tank mouth In carrying out the blanking of tank body, tank mouth by using computer, numerical control automatic cutting machine to cut at the same time, utilize well-designed fetus, complete the hot pressing molding of can mouth, and detect the can mouth of hot pressing molding, 2) through the use of feasible fetal tools, fixtures, To ensure the assembly accuracy of large cylinders and trunnions, the feasible fetal tools and fixtures are: the tank mouth pressure type fetus, to ensure the coaxiality of the trunnions on both sides of the clamping fetus, the trunnions and the cylinder ** when the horizontal assembly of the horizontal assembly of the adjustment of the fetus, in turn with these 3 sets of tires to assemble the large cylinder and trunnions, 3) the development of torpedo tank welding process a) analysis of the weldability of the steel used, the selection of preheating temperature 200 250, slow cooling after welding and immediately for stress relief, b) selection of welding materials and process parameters according to the weldability analysis, Base metal situation and the use of torpedo tanks, choose low-hydrogen alkaline electrodes for positioning welding, choose mixed gas shielded welding with small welding deformation, small line energy and continuous welding, and use narrow channel multi-layer welding, c) Welding cylinder and trunnion Before welding, first use a grinder to polish and clean the groove and welding area, use manual arc welding positioning welding after docking, and check that the groove surface is qualified for magnetic particle inspection, and the steel plate and trunnion welding area are evenly preheated to 200 250, and the low-hydrogen alkaline electrode is 350 before positioning welding Drying for two hours, select the current 150 160A, symmetrical positioning welding firmly, use the wind hammer hammering method to eliminate interlayer stress while welding, when the groove is welded to 2 3 deep, the tank body is rotated on the rotating tire, the carbon arc gouging the inner welding root, the grinding wheel grinding, symmetrical welding after PT inspection until the welding is full, after welding, continue to heat and cool slowly with gas, insulate with asbestos, dehydrogenation, carry out ultrasonic flaw detection inspection on the weld, and RT detection is carried out at the T-shaped joint position.

It's better to let a professional operate this kind of thing.

Torpedo-type molten iron tanks, generally referred to simply as torpedo canisters, are equipment used to hold and transport molten iron.

A water tank is a device used to hold and transport molten iron. There are two types of open iron water tanks and torpedo iron water tanks. The open iron water tank has a hot metal ladle; The torpedo-type iron water tank is also referred to as the mixed iron car. Torpedo-type molten iron tanks are widely used in large and medium-sized iron and steel enterprises abroad.

It belongs to the metallurgical furnace in the professional kiln.
