Abstract
The invention discloses a constructing method of entire ladle casting and lining, which comprises the following steps: locating mould, assembling at least three locating blocks on the bottom of ladle, distributing the blocks on the periphery of ladle bottom, setting wedge angle in the locating block to make diameter of encircle of each locating block bottom more than the diameter of excircle on the mould bottom, adopting the same material for each locating block and ladle lining.
Description
Technical field
The invention belongs to anti-unit construction technical field, particularly relate to the construction method of a kind of ladle integral pouring and casing pouring liner.
Background technology
In ladle integral pouring construction for guaranteeing the cylinder-packing consistency of thickness and the demoulding smoothly of construction back, need to loose tool carry out high-precision location and guarantee to construct after loose tool effectively separate with cylinder-packing.
It is highly general more than 2 meters for large-scale ladle, thus cause location, ladle bottom inaccurate, construction back demoulding difficulty, this is a ubiquitous problem in the ladle integral pouring liner.
Summary of the invention
The object of the invention is to provide the construction method of a kind of ladle integral pouring and casing pouring liner, can realize the accurate location and the demoulding smoothly of loose tool.
For achieving the above object, technical scheme of the present invention is: the construction method of a kind of ladle integral pouring and casing pouring liner, the location, the installation steps that comprise mould, it is characterized in that: in described mould location, installation steps, the mode of laying locating piece at ladle bottom is adopted in the mould location, described locating piece is at least three, be evenly distributed on the ladle bottom periphery, inboard at locating piece is provided with the angle of wedge, make each locating piece bottom inscribed circle diameter equal or be slightly larger than the mold bottom outside diameter that the material of each locating piece is identical with the material of ladle liner.
Described locating piece can be cube, also can be other shape cylinders, prism or the like, and the described angle of wedge is made of the chamfering on this cube top.
The quantity of described locating piece is four, five or six.Generally speaking, ladle is big more, and required locating piece quantity is many more, and the specification of locating piece then can be determined according to the thickness of ladle liner.
In described mould location, installation steps, also be included in the mould outside and smear lubricant, and outside lubricant, lay the step of separation layer.
Described separation layer can be plastic sheeting, paper, oilpaper or malthoid.Described lubricant can be lubricating grease, machine oil or aquadag.
The construction method of ladle integral pouring of the present invention and casing pouring liner has the following advantages:
1. because employing is laid locating piece at ladle bottom, can make that the loose tool position fixing process becomes simple, convenient, precision is high, and locating piece also can not produce mould and interferes when taking out, and the material of locating piece is with to water the material feeding material identical, locating piece becomes the part of working lining and needn't take out again after cast, simple to operate, thereby the accurate location that can realize mould, guarantee that ladle liner solidifies the back mould and deviates from smoothly.
2. smear lubricant in the mould outside, and lay separation layer outside lubricant, knockout course is become efficiently, reliably, one time demoulding success rate is 100%.Can also alleviate simultaneously labor strength and enhance productivity.
3. owing to adopt lubricants such as lubricating grease, machine oil or aquadag as interleaving agent, adopt materials such as plastic sheeting, paper, oilpaper or malthoid as separation layer, its construction is simple, and material is easy to get, demoulding success rate height.

The specific embodiment
The construction method of ladle integral pouring of the present invention and casing pouring liner, the location, the installation steps that comprise mould, in described mould location, installation steps, determining the quantity of locating piece and the size of locating piece according to the ladle size that will pour into a mould and the thickness of ladle liner, is example explanation construction method of the present invention below with reference to Fig. 1, Fig. 2 with integrated poured permanent layer:
At first evenly lay five cubic locating pieces 1 at the ladle bottom periphery, as shown in Figure 2, the radial width of locating piece 1 equals the thickness of the permanent layer 6 that will pour into a mould, as 110 millimeters, inside upper part at locating piece 1 is provided with chamfering 2, referring to Fig. 1, make each locating piece 1 form up big and down small taper and its bottom inscribed circle diameter and equal or be slightly larger than mould 3 bottom outside diameters, and the material of each locating piece 1 is identical with the material of permanent layer 6.
Secondly, smear machine oil at mould 3 outer walls that are used to pour into a mould permanent layer 6 and constitute machine oil layer 4, and machine oil layer 4 outside laying plastic sheeting 5 separation layers, plastic sheeting 5 is pasted on mould 3 outer walls.
Then mould 3 is hung in the ladle shell 7, mould 3 bottom margins slip into ladle shell 7 bottoms along the inboard chamfering 2 of locating piece, finish the accurate location to mould 3.
At last, inject and water material feeding, cast permanent layer 6 was treated permanent layer 6 air dries after 24 hours, took out mould 3, owing to be provided with separation layer on mould 3 surfaces, the back mould 3 that can guarantee to construct separates effectively with permanent layer 6, can at an easy rate mould 3 be taken out.
