For example, the Chinese patent whose patent number is CN106540961B discloses "a kind of billet assembly method for the production of extra-thick steel plates by vacuum composite technology", and the Chinese patent with the patent number CN106345809B discloses "a method for forming blanks by using vacuum composite technology to produce extra-thick steel plates". ", the latter also needs to evenly spread nickel powder on the contact surface, the process is complicated, the implementation is difficult, and the production time and production cost are increased
In addition, vacuum electron beam welding requires a large one-time equipment investment and high equipment maintenance costs, which limits its application range

Embodiment Construction
[0019] A low-cost and high-efficiency composite billet assembly process method described in the present invention comprises the following steps:
[0020] (1) Blank pretreatment; after the composite surface of the composite blank is milled and ground, the surface is cleaned; then the grooves are processed on the four sides of the composite surface;
[0021] (2) Assembling blanks; performing upper and lower composite assembly of the 2 blanks to be compounded to ensure that the composite surfaces are aligned;
[0022] (3) Bottom welding is fixed; use electrode arc welding or manual gas shielded welding to carry out bottom welding along the groove, and leave a section at least 20mm long as an air outlet; the thickness of the welding meat is not less than 2mm; After finishing, use the blank turning machine to place the composite blank upright, that is, the long side of the composite blank is in a vertical state;
[0023] (4) Surrounding sealing welding; use the gas-electric vertic...

Abstract
The invention relates to a low-cost and high-efficiency composite blank assembling process method. The method comprises the following steps of (1) blank pretreatment; (2) blank assembling; (3) backingwelding fixing; (4) periphery seal welding; and (5) vacuumizing and sealing. According to the low-cost and high-efficiency composite blank assembling process method, electro-gas welding equipment isadopted to replace vacuum electron beam equipment to weld composite blanks, the one-time investment and daily maintenance cost of the equipment can be greatly reduced, preheating is not needed duringwelding especially to steel materials with the C content being 0.1 wt% or below, the interface bonding force can be greatly improved, and the welding operation time is shortened.
Description
technical field [0001] The invention relates to the technical field of composite plate rolling, in particular to a low-cost and high-efficiency composite billet assembly process method. Background technique [0002] With the vigorous rise of infrastructure such as high-rise buildings, cross-sea bridges, deep-sea oil production platforms, and large-scale hydropower stations, the special-thick steel plates used in the manufacture of major technical equipment such as boilers and pressure vessels, heavy machinery, nuclear power, wind power, hydropower, and construction bridges The demand is increasing. Many enterprises at home and abroad use the compound rolling method to produce extra-heavy steel plates, and the welding and assembly of extra-heavy steel plate mother blanks has become a key step in the production of rolling compound extra-heavy plates, and it is also an important factor affecting the production efficiency of rolling compound extra-heavy plates. factor.
