Abstract

It relates to the charge sectional tamping method for smelters, starting from tamping of fire resistant charge, putting sectional tamping furnace ring made of bottom and the ring frame into the cavity, with the frame divided at least in two sections, frames surrounding the ring bottom, with adjacent two frames having same joint shape and positioned by plugs, tamping from the bottom tamping furnace ring, tamping the fire resistant charge inside the gap between the surrounding area of the frames through fork lever. Adding fire resistant charge can clearly see and eliminate impurity substance, it is hard to mix impurities dropped out from the insulation material of the cavity insulators.

Description

A kind of furnace charge segmental-tamping method of power frequency smelting furnace

Technical field

The invention belongs to the power frequency smelting furnace improvement of using method in actual use of casting usefulness.

Background technology

When power frequency smelting furnace uses in reality, to the fire-resistant furnace charge of one deck be set heat-barrier material cavity (barrel) inwall in coil, traditional method to set up is to use whole furnace beating ring, after the heat-barrier material cavity bottom adds fire-resistant furnace charge tamping, whole furnace beating ring is inserted cavity, evenly reserve the gap between whole furnace beating ring periphery and the heat-barrier material cavity, in the gap, add the fork arm tamping of fire-resistant furnace charge then, because the circle wall of whole furnace beating ring is dark, run into the heat-barrier material cavity during with the fork arm tamping easily, make the cavity heat-barrier material come off, form the impurity of fire-resistant furnace charge, also have, when in adding fire-resistant furnace charge process, sneaking into impurity, one be difficult for to find, easy-clear not after the two is found.Also has whole furnace beating ring complex manufacturing technology, the cost height.

Summary of the invention

Come off for fear of the cavity heat-barrier material, add and find easily in the fire-resistant furnace charge process and remove and sneak into impurity, reduce the furnace beating ring cost simultaneously, the present invention adopts segmental-tamping method.

The present invention realizes like this, after the heat-barrier material cavity bottom adds fire-resistant furnace charge tamping, furnace beating ring is inserted cavity, evenly reserve the gap between furnace beating ring circle frame periphery and the heat-barrier material cavity, in the gap, add the fork arm tamping of fire-resistant furnace charge then, furnace beating ring is a section furnace beating ring, section furnace beating ring is made of the circle end and circle frame, at least two sections of circle frames, bottom one section furnace beating ring bottom is the circle end, circle is the circle frame at the end, and other each section is the circle frame, and adjacent two ring frame interface shapes are identical, locate with latch between the two ring frame interfaces, the furnace beating ring of at first inserting cavity is bottom one section furnace beating ring, after the tamping of bottom one section furnace beating ring circle frame periphery, inserts its preceding paragraph circle frame, enclose between the frame with behind the latch location, in the gap that circle frame periphery is evenly reserved, add the fork arm tamping of fire-resistant furnace charge, use same quadrat method, successively with the fire-resistant furnace charge tamping of whole section furnace beating ring circle frame peripheries.

Every section high 250-300mm of above-mentioned section furnace beating ring circle frame.

The specific embodiment

As Fig. 1, section furnace beating ring is made of the circle end and circle frame, it is characterized in that: at least two sections of circle frames, bottom one section furnace beating ring bottom is the circle end, and circle is the circle frame at the end, and other each section only is the circle frame, adjacent two ring frame shapes are identical, locate with latch between two ring frames.

Coil is 1, after heat-barrier material 2 cavity bottoms 3 add fire-resistant furnace charge 4 tampings, one section furnace beating ring 5-1 inserts cavity with the bottom, evenly reserve gap 6 between furnace beating ring 5-1 periphery and heat-barrier material 4 cavitys, in gap 6, add fire-resistant furnace charge 4 fork arm tamping then, furnace beating ring is five sections furnace beating rings, five sections furnace beating rings are exactly the shape according to whole furnace beating ring, make five sections, the furnace beating ring of at first inserting cavity is bottom one section furnace beating ring 5-1, bottom one section furnace beating ring 5-1 bottom lock, after the tamping of bottom one section furnace beating ring 5-1 periphery, align as Fig. 2 and to insert its preceding paragraph furnace beating ring 5-2, after using latch 7 location between two sections, in the gap that the preceding paragraph furnace beating ring 5-2 periphery is evenly reserved, add fire-resistant furnace charge 4 fork arm tamping, use same quadrat method, successively with whole section furnace beating ring 5-3,5-4, fire-resistant furnace charge 4 tampings of 5-5 periphery.Every section high 250mm of above-mentioned section furnace beating ring.

After the fire-resistant furnace charge tamping with whole section furnace beating ring peripheries, in furnace beating ring, put into the material of the melting of wanting, melting is carried out in energising, the material of the melting of wanting and furnace beating ring fusing, the fire-resistant furnace charge sintering between furnace beating ring and the cavity heat-barrier material forms crucible, can repeatedly use, after crucible is scrapped, crucible is knocked out, make again with method of the present utility model.

Claims

1, a kind of furnace charge segmental-tamping method of power frequency smelting furnace, after the heat-barrier material cavity bottom adds fire-resistant furnace charge tamping, furnace beating ring is inserted cavity, evenly reserve the gap between furnace beating ring circle frame periphery and the heat-barrier material cavity, in the gap, add the fork arm tamping of fire-resistant furnace charge then, it is characterized in that: furnace beating ring is a section furnace beating ring, section furnace beating ring is made of the circle end and circle frame, at least two sections of circle frames, bottom one section furnace beating ring bottom is the circle end, circle is the circle frame at the end, and other each section is the circle frame, and adjacent two ring frame interface shapes are identical, locate with latch between the two ring frame interfaces, the furnace beating ring of at first inserting cavity is bottom one section furnace beating ring, after the tamping of bottom one section furnace beating ring circle frame periphery, inserts its preceding paragraph circle frame, enclose between the frame with behind the latch location, in the gap that circle frame periphery is evenly reserved, add the fork arm tamping of fire-resistant furnace charge, use same quadrat method, successively with the fire-resistant furnace charge tamping of whole section furnace beating ring circle frame peripheries.

2, the furnace charge segmental-tamping method of power frequency smelting furnace as claimed in claim 1 is characterized in that: every section high 250-300mm of section furnace beating ring.
