Abstract
The invention discloses an abutting device and method of a blast furnace blast belly pipe. The abutting device is composed of a bulb abutting component and an oblique insertion pipe abutting component, wherein the bulb abutting component is formed by welding a first base, a first locating pipe, a second locating pipe, a first locating plate and a rib plate; and the oblique insertion pipe abutting component is composed of a second base, a column, a second locating plate and an oblique insertion pipe locating lever. The abutting method is used for accurately locating the belly pipe on the basis of the abutting device. The invention implements the blank (finished) belly pipe abutting method, solves the problems of difficulty in measurement of spacial perpendicularity and angle and difficulty in ensuring tolerance, greatly enhances the product quality and work efficiency, and is an advanced machine manufacturing technique.
Description
technical field [0001] The invention relates to the technical field of manufacturing a blast furnace air blowing pipe, in particular, the present invention relates to a matching device and a matching method for a blast furnace blowing pipe. Background technique [0002] The blast furnace air supply device is a channel for conveying the hot air from the hot blast stove to the inside of the blast furnace, and also undertakes the task of injecting coal powder to the blast furnace. It is the key equipment of the blast furnace body system. The direct blow pipe, the core component of the blast furnace air supply device, is a weak link in the air supply system. The shape of the direct blow pipe is limited by the size and must meet the needs of the air inlet area. The structure design of the direct blow pipe is relatively complicated and difficult to manufacture. Consumable parts in a complete set of air supply equipment. [0003] Straight pipe structure such as figure 1 As shown,...
