Automatic processing device for on-line hook face groove of furnace shell of super-huge type blast furnace

Abstract

The invention relates to a cutting device, in particular to a cutting device for a large equipment circular seam. An automatic processing device for an on-line hook face groove of a furnace shell of a super-huge type blast furnace comprises automatic cutting equipment, an annular guide rail is arranged nearby the large equipment circular seam, and the automatic cutting equipment is arranged on the annular guide rail and can be movably connected to the guide rail along the guide rail through a guide wheel mechanism; a positioning guide mechanism comprises a guide wheel transverse arm connected to the top of the automatic cutting equipment and a vertical guide wheel adjusting arm connected to the guide wheel transverse arm through a cross-shaped sleeve, the end of the guide wheel transverse arm is sleeved with a spring and a nut, and one end of the spring abuts against the guide wheel adjusting arm; a guide wheel is arranged below the guide wheel adjusting arm and abuts against the guide rail side; and the automatic cutting equipment extends out to form a cutting arm wound on the lower portion of the guide rail, and the end of the cutting arm is connected with a cutting gun with the adjustable angle. According to the automatic processing device, the cutting quality is effectively guaranteed, the cutting efficiency is improved, the manpower cost is reduced, and the comprehensive benefits are improved.

Description

technical field [0001] The invention relates to a super-large blast furnace rapid maintenance device, in particular to a device for opening and processing the curved butt weld groove of the blast furnace shell. Background technique [0002] In order to reduce downtime losses, the blast furnace overhaul project generally only takes about three months. The overhaul requires horizontal cutting and beveling of the online circular seam of the old hearth section (thickness 90mm), the diameter of the circular seam cutting of the furnace shell is 16400mm, and the circumference is about 52 meters. If conventional manual cutting is used, in order to ensure the welding quality, a lot of repair and grinding work is required on the cutting surface. It is planned to arrange 20 people to work in shifts, and the construction period is about 4 to 5 days. Due to various unfavorable factors such as many obstacles on the construction site, the cutting of the furnace shell annular seam and the...

Problems solved by technology

Flame precision fast cutting and precision plasma arc cutting have very high requirements on the cutting nozzle, which increases the cutting cost virtually; the same is true for laser cutting and high-pressure water jet cutting, while CNC cutting requires computer control. These sophisticated equipment Cannot adapt to the harsh construction environment of the site at all

The above cutting methods are restricted by the on-site environment, and the input cost is relatively high
