Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

Referring to Fig. 1~Figure 12, the utility model mainly includes baking and thermal insulation cover 7, base 11, mud set pressing plate 5, the and of cross bar 1 Two pressing plate push rods 14.

Mud cover pressing plate 5 by 20mm or so general steel plate cutting form, mud cover cast manufacturing process in, play backgauge, Binder, the effect for making mud set surfacing, it welds multiple anti-skidding horizontal stripes 12 towards the one side outside stove, can be with pressing process Prevent pressing plate push rod 14 from slipping.

Base 11 is in " returning " word shape, is formed with thickness 10mm or so steel plate cutting, and the mm of its length and width about 850 × 600mm, the front end of base 11 are provided with deep 15mm, wide 30mm or so pressing plate neck 13, rear end weldering push rod block 15；Both sides respectively weldering one Individual handle 10, the common oxygen that handle 10 is curved " ︵ " shape by pipe are made, and highly less than 120mm, prevent too high influence clay gun It is rotationally advancing.Base 11 and pressing plate push rod 14 coordinate, and are mainly used in compressing mud set pressing plate 5.

Hook 2 is cut into by the general steel plate that thickness is 20mm or so, links up with the external diameter 180mm on 2 heads or so, internal diameter 140mm or so, upper and lower two pairs, it is soldered directly on stove skin.After mud set casting complete, upper and lower two cross bars 1 are fixed by hook, are prevented Mud set pressing plate 5 retreats.

Baking and thermal insulation cover 7 is made up of 3mm or so sheet metal, and the baking fire that diameter 150mm or so is opened in centre inserts hole 16, Gas piping is may be inserted into, air-permeating hole is opened in four sides many places.Before mud set pressing plate is placed in after mud set casting complete, 8 pairs of insertion baking fire Mud set carries out baking and thermal insulation, until mud set coagulation forming.Baking and thermal insulation cover 7 plays uniformly baking with preventing that toast flare is scraped by wind The effect gone out.

Use process：

（1）Welding hanging hook.Two pairs are first welded on stove skin（4）Rectangle is presented centered on iron mouth eye in hook, four hooks Distribution, rectangular aspect about 950 mm × 400mm, can according to mud cover size be finely adjusted, hook weld after can Reusability, Without welding again.

（2）Handle old mud set.Centered on iron mouth eye, scratch big outer small in diameter 450mm or so, depth 180mm or so The hole of " as pin " shape.

（3）Put base mud set pressing plate.Before base is placed in into old mud set, and pressing plate lower end is inserted in pressing plate neck, mud Outward-dipping 10 ° or so of pressing plate is covered, is easy to loading mud set castable, its upper end or so to be withstood with two pressing plate push rods 14, prevents Mud set pressing plate is toppled over.

（4）Suppress mud set.After casting complete with stokehold clay gun compress forward mud set pressing plate and with fire baking, repeatedly compacting and Baking 3 times, makes mud jacking gradually be compacted, and as mud set pressing plate pushes up forward, pressing plate push rod is descending under gravity, lasting to compress Mud covers pressing plate, prevents mud set pressing plate from retreating and gap occur.

（5）Remove pressing plate push rod, baking mud set.After mud set compacting, by two cross bars directly through hook, mud set pressing plate is blocked Retreat route.Pressing plate push rod is removed again.Finally thoroughly toasted with gas fire, mud set completes.

The utility model is simple in construction, strong adaptability, can standardize complicated pouring mud sleeve job simplification.It is applied to The cast of mud set and repairing of domestic and international each blast furnace taphole.The device can quickly and accurately suppress the taphole mud sleeve of high quality, keep away When exempting from conventional apparatus pouring mud sleeve, particularly mud set repairing cast, mud, pressure are run caused by step is complicated, instrument is various Low intensity processed, compacting out-of-flatness, the problems such as baking temperature is uneven, and mud set is easy to crack, substantially reduce mud set Production Time.
