Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model by increasing sleeve pipe between the furnace shell outer wall and bearing assembly of the cold rolling continuous belt steel annealing furnace of tradition, to adapt to the refractory thickness of different thickness, enable the use of the furnace roller of same length under different heat treatment modes, thus reduced the kind of furnace roller.
As shown in Figure 1, the cold rolling continuous belt steel annealing furnace of the utility model embodiment comprises furnace shell 10 and is arranged on the furnace roller 5 of furnace shell inside, the length of furnace roller 5 is default fixed value, the fore side of furnace roller 5 and back side are separately installed with bearing assembly 1, furnace shell 10 inwall has built refractory materials 4 by laying bricks or stones, be equipped with sleeve pipe 3 between the bearing assembly 1 of furnace roller 5 both sides and furnace shell outer wall, be sleeved on furnace roller.Due to sleeve pipe 3 and extraneous contact, the heat on the furnace shell 10 contacted with it and furnace roller 5 can also be passed, enhance radiating effect.
In cold rolling continuous belt steel annealing furnace described in the utility model, this annealing furnace comprises the sleeve pipe 3 of the multiple length adapting to different thickness refractory materials, if annealing furnace also has the length of miscellaneous part or the change of thickness, then also can the length of corresponding change sleeve pipe 3, with the length of unified furnace roller 5 used.
In the utility model embodiment, be the details drawing of sleeve pipe 3 as shown in figs.3 a and 3b, sleeve pipe 3 comprises seamless tube 31, outside one end of seamless tube 31, surrounding is fixed with the first base plate 32, outside the other end of seamless tube 31, surrounding is fixed with between the second base plate 33, first base plate 32 and the second base plate 33 and is connected with gusset 34.
In an embodiment of the present utility model, the first base plate 32 is by airtight welding at furnace shell 10 outer wall, and the second base plate 33 is connected by fastening piece 2 with bearing assembly 1.
Because the heat treatment mode of each section of continuous heat treating furnace is different, in stove to build layer (i.e. refractory materials 4) thickness by laying bricks or stones different, like this in the furnace roller length also corresponding difference adopting roller-way conveying belt steel, in order to reduce the kind of the furnace roller of same material, can first the maximum length of furnace roller required in cold rolling continuous belt steel annealing furnace be calculated.
In an embodiment of the present utility model, can also require to be filled with vacuum forming fiber brick between sleeve pipe 3 and furnace roller 5 according to furnace temperature.
As shown in Figure 1, if sleeve pipe 3 length is h, fire-resistant building layer (i.e. refractory materials 4) thick L2, furnace width is L1, sleeve pipe 3 place of fore side be L3 to fore side axle head distance, and sleeve pipe 3 place of back side is L4 to the distance of back side axle head, and the distance between fore side sleeve pipe 3 outer face and back side sleeve pipe outer face is L5, see figures.1.and.2 and can obtain: L=L3+L4+L5, and L5=2 (h+t+L2)+L1.Analyze above formula, known furnace width L1, furnace shell wall thickness t are generally fixed values in continuous annealing furnace, the thickness L2 of refractory materials 4 is changing values, L3 and L4 is also substantially constant, like this to unified each stove section furnace roller length, then require that L is definite value, the length h of amendment sleeve pipe 3 adjusts because the thickness L2 of refractory materials 4 or other size change required amendment.In particular cases, as shown in Figure 3 B, the first base plate 32 (length t1) of sleeve pipe 3 and seamless tube (length h0)) can, only stay the second base plate 33 (length t2).
When installing furnace rolls road, first furnace roller 5 is put into stove, fill or not filled vacuum shaping fiber brick 7,8 by furnace temperature requirement, if then load sleeve pipe 3(to be filled with vacuum forming fiber brick 7, it is outer that sleeve pipe 3 is sleeved on vacuum forming fiber brick 7), fore side bearing assembly 1(or back side bearing assembly 6), fastening piece is adopted to be linked together by above-mentioned parts, then carry out installation location, to be positioned work well after the first base plate 32 of sleeve pipe 3 can be carried out airtight welding with furnace shell 10.Now the base plate of sleeve pipe 3 and upper welding thereof is equivalent to the mounting base of existing furnace roller bearing assembly, and the mounting base (i.e. sleeve pipe 3) of furnace roller bearing assembly can be welded on furnace shell 10 to become to be integrated after mounting.During dismounting, only need take off bearing assembly 1 or 6, fastening piece 2, furnace roller 5 etc., convenient and swift.
Under different heat treatment mode, if the thickness of required refractory materials 4 is different, then can pass through the sleeve pipe changing different lengths, and without the need to changing furnace roller, thus furnace roller kind is greatly reduced.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to the utility model claims.
