The invention relates to the field of the manufacture of a wide
thick plate blank for a wide
thick plate rolling
machine, in particular to a tooling for efficiently manufacturing the wide
thick plate blank for the wide thick plate rolling
machine and an efficient manufacture method of the wide thick plate blank, aiming at the problems such as cavity shrinking, loosing and
cracking and the like of the plate blank and the low manufacture efficiency. The manufacture tooling is provided with a pouring
system, an
ingot mould, an insulated feeder, a pouring trolley, an
automatic control pouring
transit line, a heat preservation cover and a burial pit. Before pouring, the
ingot mould, the pouring
system and a
chassis are assembled on the pouring trolley, and the insulated feeder is preheated. The pouring is carried out slowly; after pouring, high-temperature demolding is carried out, and the temperature of a steel
ingot is kept by the heat preservation cover; and then the steel ingot is carried away by the trolley, and is hoisted into the burial pit to be slowly cooled. Finally, a flash groove is
cut out of the wide thick plate, so that the flashes and strains can be removed, and the wide thick plate is put into a
thermal treatment furnace to be annealed. The tooling and the method are applicable to the production of the thick plate blanks with thickness of 350-1200mm and weight of 20-70 tons.
