Problems solved by technology

[0002] Problems existing in traditional cast steel slag pots: 1. The casting process consumes a lot of energy and takes a long time; 2. The slag pots are severely cracked and difficult to repair and costly to repair under extremely cold and hot conditions; 3. The main reasons are The casting material and manufacturing process cannot effectively improve the cracking problem, and the service life is short
Other problems existing in welding slag tanks: 1. According to general working conditions, low-alloy structural steel is used as the container material, resulting in low safety factor and poor deformation resistance; 2. Some trunnion seats are connected with flanges and trunnions, which is difficult to process. The cycle is long and the cost is high; some adopt the "cross seat" welding method, which has a small safety factor of bearing capacity and large deformation due to poor rigidity; self-weight load
The bottom ring seam is the weld seam with the largest impact force and static load, and the weld seam wears a lot; 4. There is no water storage structure on the outside, the cooling water flows away instantly, and the cooling effect is poor; 5. When the slag tank is in use, because it is extremely Extremely cold and hot, and with cooling water spray, the outside is easy to rust, and long-term rust and peeling reduce the wall thickness of the cylinder, thereby reducing the service life

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] refer to Figure 1 to Figure 7 As shown, the new environmentally friendly and long-life welded slag tank in an embodiment provided by the present invention includes a cylinder body 1 and a bottom plate 5, the bottom of the cylinder body 1 is connected to the bottom plate 5 through a circumferential weld, and the cylinder body 1 is made of low alloy It is welded by high-strength heat-treated rolled steel plates. There are multiple circumferential reinforcements 7 on the outside of the cylinder 1, and multiple vertical reinforcements 8 between the circumferential reinforcements 7. Symmetrical positions on both sides of the cylinder 1 are set. There are trunnions 2; the manufacturing process of the welded slag tank is low-carbon and environmentally friendly. The entire manufacturing process mainly involves pressing and welding. It does not need to...

Abstract

The invention discloses a novel environment-protection and long-life welding type slag ladle. The slag ladle comprises a cylinder and a baseplate, wherein the bottom of the cylinder is connected with the baseplate through an annular welding line; the cylinder is welded by a low-alloy and high-strength heat treatment rolled steel plate; multiple annular ribs are arranged at the outer side of the cylinder; multiple vertical ribs are arranged among the annular ribs; and lug shafts are arranged at the two sides of the cylinder. The slag ladle has the characteristics of low carbon, environmental protection, long service life, easy repair, cost saving, corrosive medium erosion resistance and brittle fracture resistance.
