Abstract
The invention discloses a continuous annealing technology of glass tableware. A groove-shaped channel-type annealing furnace is adopted in the technology. Through a transmission belt, glass tableware undergoes six-warm-area annealing treatment at uniform speed. Thus, plasticity and toughness of the glass tableware are improved, chemical composition is homogenized, and mechanical strength and hot-cold resistance of the glass tableware's glass are enhanced. Temperature and time for heat treatment of the glass tableware are accurately controlled. Thus, thermal stress and residual stress of the glass tableware are effectively removed, mechanical strength and impact resistance of the glass tableware are raised, and the self-explosion problem of the glass tableware is effectively solved.
Description
Technical field
The invention belongs to glass working arts field, be specifically related to a kind of dinner glass continuous way annealing process.
Background technology
Glass is the non-conductor of heat, when glass is heated or cooled, will stand violent uneven variations in temperature, produces sizable temperature difference at inside glass.The glass surface temperature being directly heated during heating is high, and the inside glass temperature being indirectly heated is low, and the heated glass outer layer that at this moment temperature is high makes every effort to expand to surrounding expansion.And internal layer is because temperature is low, expand not have outer layer so much.So, glass outer will be because inner layer glass expands not to inner layer glass one tension force, and inner layer glass to be made is followed and oneself expanded together, and inner layer glass, will be to glass outer one pressure then because of glass outer superdistension, to suppress the expansion of glass outer.Inside glass this pair is because expanding active force that is inconsistent and that bring everywhere, it is simply that the stress tensile stress of inside glass and compressive stress, stress can cause glass to burst the most to a certain extent.
Summary of the invention
It is an object of the invention to provide a kind of dinner glass continuous way annealing process, control short annealing by Baltimore groove channel-type annealing furnace six warm area continuous way precision and eliminate stress technique, completely eliminate the stress of secondary operations in dinner glass, enhance dinner glass self anti-wind pressure, cold and summer-heat, impact, improve plasticity and the toughness of dinner glass, make physical property change, molecular structure more homogenization, efficiently solves the phenomenon that dinner glass occurs to burst voluntarily.
The technical solution adopted in the present invention is, a kind of dinner glass continuous type precise control annealing technology, this technology uses Baltimore groove channel-type annealing furnace, by transmission belt, dinner glass is passed in and out stove and accurately controls the speed of processing with six warm areas, at the uniform velocity to make annealing treatment dinner glass local；Dinner glass is put and is spaced apart 1cm, and six described warm areas are divided into: preheating zone, heating zone, high-temperature region, cooling one district, 2nd district that lower the temperature, Temperature fall district.
Six warm area temperature are respectively set as: preheating zone: 50～278 DEG C, heating zone: 278～480 DEG C, high-temperature region: 480～455 DEG C, and lower the temperature a district: 455～268 DEG C, and lower the temperature 2nd district: 268～165 DEG C, Temperature fall district: 165～50 DEG C.Six warm area temperature are respectively set as: preheating zone: 50～278 DEG C, heating zone: 278～480 DEG C, high-temperature region: 480～455 DEG C, and lower the temperature a district: 455～268 DEG C, and lower the temperature 2nd district: 268～165 DEG C, Temperature fall district: 165～50 DEG C.
A kind of dinner glass continuous way annealing process of the present invention, is further characterized in that: described dinner glass annealing time is 56 minutes, 16 time periods, and the time entering six warm areas is controlled as: entering preheating zone was 2 time periods, from 0～7 minute；Entering heating zone was 3 time periods, from 7～17.5 minutes；Entering high-temperature region was 3 time periods, from 17.5～28 minutes；Entering cooling one district was 3 time periods, from 28～38.5 minutes；Entering cooling 2nd district is that 2 time periods were from 38.5～45.5 minutes；Entering Temperature fall district was 3 time periods, from 45.5～56 minutes.
Six described warm areas, in addition to Temperature fall district, each warm area of annealing furnace all uses electrothermal quartz tube to heat.
Owing to the temperature and time of dinner glass heat treatment is accurately controlled, effectively removes the thermal stress in dinner glass and residual stress, improve the mechanical strength of dinner glass, cold-and-heat resistent performance and impact resistance, efficiently solve the phenomenon that dinner glass occurs to burst voluntarily.
The proportion of goods damageds substantially reduce simultaneously；While improving production capacity and yield rate, greatly reduce production cost, improve the economic benefit of enterprise.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in detail:
A kind of dinner glass continuous way annealing process, this technology uses groove type channel-type annealing furnace, by transmission belt so that dinner glass at the uniform velocity to use six warm areas make annealing treatment, dinner glass is put and is spaced apart 1cm, six described warm areas are divided into: preheating zone, heating zone, high-temperature region, cooling one district, 2nd district that lower the temperature, Temperature fall district, six warm area temperature are respectively set as: preheating zone: 50～278 DEG C, heating zone: 278～480 DEG C, high-temperature region: 480～455 DEG C, lower the temperature a district: 455～268 DEG C, lower the temperature 2nd district: 268～165 DEG C, Temperature fall district: 165～50 DEG C.
Described dinner glass annealing time is 56 minutes, 16 time periods, and the time entering six warm areas is controlled as: entering preheating zone was 2 time periods, from 0～7 minute；Entering heating zone was 3 time periods, from 7～17.5 minutes；Entering high-temperature region was 3 time periods, from 17.5～28 minutes；Entering cooling one district was 3 time periods, from 28～38.5 minutes；
