Abstract
The invention discloses a kind of abrasive wheel for abrasion of steel ball drying means, carry out in conventional drying stove, Drying Technology Parameter: incubation at room temperature 48 hours; Be warmed up to 30 DEG C with 2 ~ 5 DEG C/h, be incubated 24 hours; Be warmed up to 50 DEG C with 1 ~ 2 DEG C/h, be incubated 24 hours; Be warmed up to 80 DEG C with 2 ~ 3 DEG C/h, be incubated 48 hours; Cool to 60 DEG C with-3 ~-4 DEG C/h, cool to 40 DEG C with-4 ~-5 DEG C/h, then Temperature fall is to room temperature.Thermal source is sent in drying oven by pipeline, by Valve controlling air inflow by the hot-air of the generation in gas vehicle formula kiln temperature-fall period.The present invention effectively controls the speed per hour in heating-cooling stage, avoid the appearance of the wet blank not dry phenomenon in inside and emery wheel and pad contact face through-thickness crackle because dry speed causes billet surface dry and cracked soon, yield rate brings up to more than 99.99%, improves production efficiency.Meanwhile, owing to adopting UTILIZATION OF VESIDUAL HEAT IN, be conducive to increasing economic efficiency.
Description
Technical field
The present invention relates to a kind of ceramic binder for steel ball grinding wheel drying means, be mainly used in the emery wheel making grinding spherical balls.
Background technology
Abrasive wheel for abrasion of steel ball is for the special grinding wheel of grinding diameter at below 76.20mm spherical balls, has the features such as specification is large, fine size, hardness are high, density is large, is widely used in machinery, bearing industry.In general, the external diameter of abrasive wheel for abrasion of steel ball is 800mm, also has part for 900mm, 720mm; Its thickness is 100mm, therefore belongs to the emery wheel of large gauge.Meanwhile, in order to ensure that emery wheel has higher durability, use very large in conjunction with dosage, general sand knot is than being 1:1; For ensureing the fineness of grinding steel ball, the granularity of abrasive material all at F180 and with carefully, therefore emery wheel blank organize very tight, pore is few.The abrasive wheel for abrasion of steel ball of large for specification like this, dense structure, drying is critical process.Because blank density is large, pore is few, the outside diffusion ratio of moisture is more difficult, so wet base can not carry out rapid draing.Most producer adopts the methods such as special installation, special process, reduction rate of drying to solve this problem.But the crackle having through-thickness in the one side of emery wheel and pad contact occurs, percent defective is about 2%; And crackle is very fine, larger energy to be spent during loading of kiln to check, affect loading of kiln progress and labor productivity.
Summary of the invention
Object of the present invention is exactly the weak point overcoming existing emery wheel drying process, provides the drying process for steel ball grinding wheel that a kind of dry mass is good, crackle waste product is few, production cost is low.
Technical scheme of the present invention is: a kind of abrasive wheel for abrasion of steel ball drying means, carries out in conventional drying stove, and its improvements are to adopt corresponding drying process, and described Drying Technology Parameter is as follows:
(a), intensification, holding stage:
(b), temperature-fall period:
Further scheme is: described abrasive wheel for abrasion of steel ball drying means, and the thermal source of needs is sent in drying oven by pipeline, by Valve controlling air inflow by the hot-air of the generation in gas vehicle formula kiln temperature-fall period.
Technical solution of the present invention is owing to devising room temperature, several insulation points such as 30 DEG C, 50 DEG C, 80 DEG C, and effectively control the speed per hour of temperature rise period, therefore when carrying out drying, the speed getting rid of moisture content obtains effective control, avoids the appearance of wet blank not dry phenomenon in inside because dry speed causes billet surface dry and cracked soon; In temperature-fall period, control certain speed simultaneously, make emery wheel blank consistent with backing plate rate of temperature fall, avoid the appearance of emery wheel and pad contact face through-thickness crackle, effective guarantee product quality, yield rate brings up to more than 99.99%, special messenger must do not arranged during loading of kiln to check micro-crack, improve production efficiency.Meanwhile, because thermal source supply is the hot-air of the generation in the gas vehicle formula kiln temperature-fall period utilized, has saved production cost, be conducive to increasing economic efficiency.
Detailed description of the invention
The blank 100 that wet by 1-800*100*360-A/GC abrasive wheel for abrasion of steel ball after shaping is placed on and special blank drying cart pushes drying oven carries out drying, by pipeline, the hot-air of the generation in gas vehicle formula kiln temperature-fall period is sent in drying oven, by the Valve controlling air inflow on pipeline, thus control temperature ascending, descending in drying oven, insulation.Whole process performs by following Drying Technology Parameter.
(a), intensification, holding stage:
(b), temperature-fall period:
Dried abrasive wheel for abrasion of steel ball blank flawless waste product, does not need to use other thermals source, good in economic efficiency.
Claims (2)
1. an abrasive wheel for abrasion of steel ball drying means, carries out in conventional drying stove, and it is characterized in that adopting corresponding drying process, described Drying Technology Parameter is as follows:
(a), intensification, holding stage:
(b), temperature-fall period:
2., by abrasive wheel for abrasion of steel ball drying means described in claim 1, it is characterized in that the thermal source of described conventional drying stove is sent in drying oven by pipeline, by Valve controlling air inflow by the hot-air of the generation in gas vehicle formula kiln temperature-fall period.
