Description
Technical field
The utility model relates to the floor tube attemperator of heating furnace, is specifically related to a kind of heating-furnace bottom tube wrapping layer.
Background technology
The anchoring piece of existing heating-furnace bottom tube wrapping layer is not exposed, is inconvenient to install and operation is loaded down with trivial details; The pouring material of wrapping layer selects heavy or half heavy, and bulk density is large, and heat insulation effect is poor, and cause the waste of the energy, and traditional lightweight casting material strength is low, refractoriness under load is low, and anti-thermal shock is poor, can not meet instructions for use under the high temperature conditions; And existing wrapping layer pouring material easily comes off, service life is short, and impact is normally produced, and adds maintenance cost.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of high insulating effect, difficult drop-off, heating-furnace bottom tube wrapping layer easy for installation.
The technical scheme that the utility model solves the employing of its technical problem is:
A kind of heating-furnace bottom tube wrapping layer, the anchoring piece comprising liner and be connected with liner, described anchoring piece comprises anchor plate and is arranged on the anchoring claw of anchor plate both sides, and described liner and anchor plate are circular arc and anchor plate is embedded in the surface of liner inner arc; Described liner side arranges circular groove, and opposite side arranges the arc-shaped convex be meshed with circular groove; Described anchoring claw is arranged on liner; Described anchor plate be radian be greater than liner be radian and anchor plate two ends higher than liner two ends.
As what improve, described liner adopts high-strength light castable, preferred mullite pouring material.
As what improve, described anchoring piece adopts the trade mark to be the stainless steel of 1Cr18Ni9Ti.
As what improve, described anchoring claw is in T shape.
The beneficial effects of the utility model are,
Liner adopts high-strength low-density castable, heavy, half heavy castable better heat preservation that more traditional wrapping layer adopts, and floor tube heat insulation effect is significantly improved; Liner is circular arc, and arc groove and arc convex enable this wrapping layer and floor tube compact siro spinning technology; Wrapping layer anchoring claw is T-shaped, improves and makes a concerted effort to grabbing of castable, the wrapping layer difficult drop-off after installation, long service life; Anchoring piece is exposed, is convenient to welded and installed on floor tube.
The utility model scheme is used for successful in practice, and energy-saving benefit is high, administration measure, shortens maintenance construction period, improves productivity effect, have wide promotion prospect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model;
In accompanying drawing, 1 liner, 11 circular grooves, 12 arc-shaped convex, 21 anchor plates, 22 anchoring claws.
Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, below in conjunction with the drawings and specific embodiments in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The anchoring piece that the present embodiment comprises liner 1 and is connected with liner 1, described anchoring piece comprises anchor plate 21 and is arranged on the anchoring claw 22 of anchor plate 21 both sides, and described liner 1 and anchor plate 21 are circular arc and anchor plate 21 is embedded in the surface of liner 1 inner arc; Described liner 1 side arranges circular groove 11, and opposite side arranges the arc-shaped convex 12 be meshed with circular groove 11; It is inner that described anchoring claw 22 is arranged on liner 1; Described anchor plate 21 be radian be greater than liner 1 be radian and anchor plate 21 two ends higher than liner 1 two ends.
Described liner 1 adopts mullite pouring material.
Described anchoring piece adopts the trade mark to be the stainless steel of 1Cr18Ni9Ti.
Described anchoring claw 22 is in T shape.
