Description
Technical field:
the invention belongs to the technical field of electronic-grade float glass manufacturing, relates to a transition roller table and slag box cleaning technology, and in particular relates to a float glass transition roller table and a cleaning method of a transition roller table slag box.
The background technology is as follows:
the electronic grade float glass transition roller table and slag box system are important connecting components between a float glass tin bath and an annealing kiln, and play a decisive role in the process of entering the annealing kiln after float glass is formed. The glass ribbon coming out of the tin bath enters an annealing kiln through a transition roller table to be cooled by a reasonable temperature curve, and the requirements on temperature control and sealing cleaning of the transition roller table and a slag box system are very strict. At present, a transition roller table and a slag box system of common float glass have no sealing and cleaning device, and the following problems exist in the process of producing special float electronic glass:
the outlet of the tin bath and the upper part of the transition roller table are sealed by four sealing curtains on the upper part of the transition roller table, a gap of about 10mm is reserved between the four sealing curtains and the running glass ribbon, and as volatilized tin compounds such as tin oxide, stannous sulfide and tin metal vapor and the like enter the transition roller table and the slag box along with the high-temperature glass ribbon, the tin oxide, stannous sulfide and tin metal vapor can be attached to a ceramic roller of the transition roller table, so that the defects such as tin dipping and scratch of the glass ribbon are caused; when the bath pressure is large, the vapor of tin oxide, stannous sulfide and tin metal can enter the annealing kiln through the gap between the sealing baffle curtain and the glass ribbon and adhere to the roller way of the annealing kiln, so that the defects of regular tin dipping, scratch, impression, light spots and the like of the glass plate are caused.
2. The mixed gas of sulfur dioxide (chemical formula SO 2) and nitrogen is introduced into the transition roller table and the slag box of the float glass, SO that a sulfur dioxide protective film layer is formed on the surface of the running glass belt, the glass is prevented from being scratched and microcracked when passing through the transition roller, the sulfur dioxide of the transition roller table and the slag box can diffuse into the tin bath to pollute the protective gas atmosphere of the tin bath, and meanwhile, the sulfur dioxide can corrode the four-channel blocking curtain at the upper part of the glass belt, SO that the pollution gas such as sulfur dioxide in the slag box and the roller table needs to be removed in time.
3. The three transition rollers in the slag box are all provided with automatic tin wiping devices, graphite dust, tin compound dust and particles are generated in the tin wiping process, and inevitably fall into the slag box and float to the periphery of the glass plate and the surface of the transition roller; the four blocking curtains on the roller table can generate small dust and the like to fall onto the glass plate in the long-time burning process; when the broken glass at the bottom of the slag box is cleaned daily, glass scraps and dust can float in the slag box and the space of the transition roller table. All generated dust, particles and the like can cause defects such as roller marks, light spots and the like on the surface of the glass, and meanwhile, dust and particles attached to the upper surface and the lower surface of the glass plate can cause serious misjudgment of a glass defect detector, so that the qualification rate of the glass plate is affected.
4. The stability of the bath pressure of the tin bath is one of important indexes for ensuring the forming quality of float glass, and a positive pressure environment is formed in the bath by introducing a certain amount of mixed protection gas of nitrogen and hydrogen into the tin bath. However, when the pressure fluctuation and the sealing of the tin bath are poor, the outside ambient air enters the tin bath through the edge sealing, the observation hole, the edge drawing machine and the gap at the joint of the monitoring lens and the tin bath; air in the annealing kiln permeates into the tin bath through a gap between the sealing baffle curtain and the glass ribbon, so that tin liquid in the tin bath is oxidized and polluted, defects such as tin dipping, roll marks and light spots of the glass ribbon are caused, and the long-time tin liquid oxidation also greatly increases the production cost.
Therefore, in the production of special float electronic glass, a set of cleaning devices for the transition roller table and the slag box of the special float electronic glass are urgently needed in the transition roller table and the slag box system, so that the defects are overcome, and the quality of the electronic glass is not affected in the production process.
