Single-trolley and double-beam ladle crane with non-translating cast secondary hook

Abstract

The invention relates to a single-trolley and double-beam ladle crane with a non-translating cast secondary hook, and belongs to the field of heavy devices for metallurgy and casting innovation. The single-trolley and double-beam ladle crane with the non-translating cast secondary hook is provided with only two main beams, a main lifting mechanism and an auxiliary lifting mechanism are arranged onthe same trolley frame and are used together with a hemispherical pot-shaped ladle, the secondary hook only needs to be vertically lifted in order to complete molten steel overturning and slag cleaning, and the secondary hook and an auxiliary lifting driving mechanism do not need to move horizontally. Compared with traditional ladle cranes, the single-trolley and double-beam ladle crane has the advantages of construction simplification, unlimitation by the tonnage size, saving of the manufacturing and maintenance cost, avoiding of the slippage of secondary trolley wheels during double-dolly casting, enhancement of the stability of molten steel pouring, facilitation of the intelligentization of high-precision constant flow casting of the ladle crane, and facilitation of improvement of thequality of hot continuous rolling and casting products.

Description

technical field [0001] The invention relates to a single-carriage double-girder casting crane with a non-translational casting auxiliary hook, which is mainly used in iron and steel smelting and molten steel casting, and belongs to the category of high-precision intelligent control metallurgy and casting innovative heavy equipment. Background technique [0002] The rapid development of the domestic economy and the urgent need for infrastructure construction have promoted the improvement of my country's steel production and performance. Casting crane pouring molten steel pouring has an extremely important effect on the properties of steel. During the tipping process of the ladle, the operator only realizes the dumping of the ladle through an indirect screen, and the rotational displacement of the ladle per unit time cannot be precisely controlled; moreover, in this process, the cooperative work of ground guidance personnel is often required , to complete the entire pouring p...

Problems solved by technology

However, the steel ladles used in metallurgical casting today often adopt the traditional cylindrical design. During the overturning process of the traditional steel ladle, the running track of the auxiliary hook of the casting crane is an arc. If the molten steel is to be poured stably, the auxiliary hook of the casting crane is required The hook reciprocates with the auxiliary trolley. During this process, the start, stop and operation of the auxiliary trolley will impact the ladle, causing unnecessary vibration of the ladle and increasing the instability of the molten steel casting process, thereby affecting the finished steel and casting quality
