1. 1. Get off and take bus No.6 directly. If it's the Central Hospital, it's the stop sign of Enshi central hospital after Qingjiang
2. If it's the State Central Hospital, you can continue to take No.6 bus from the Central Hospital, go through an Enshi square, a Zhongda Imperial City, and then go to the State Central Hospital (it's not the State Central Hospital, it's called a community, forget it)
3. There are two state central hospitals. If it's the one in the center of the city, the central hospital will get off and transfer to No.2 bus in the same direction, passing through the Central Hospital in Enshi square, the power company's Shi square, Wuyang Bazhou Central Hospital (destination)
No.4 and No.6 bus will go their separate ways with No.2 bus when they arrive at the power company, So if you want to go to the State Central Hospital in the city, please transfer to No. 2 at the stations in front of the power company

2. Flue gas desulfurization technology status of sintering machine
flue gas desulfurization technology is mainly divided into dry / semi dry and wet flue gas desulfurization technology. Dry / semi dry flue gas desulfurization technology mainly includes spray rotary drying absorption process (SDA), circulating fluidized bed flue gas desulfurization process (CFB) and so on. Wet process mainly includes: limestone gypsum wet process, ammonia flue gas desulfurization process, magnesium oxide wet process, etc< (1) the annual operation rate of sintering machine is high, and the amount of flue gas emission is large 2) The composition of flue gas is complex, and there is variability according to the change of ingredients 3) The fluctuation range of flue gas temperature is 90-150 ℃ 4) The humidity of flue gas is relatively high, generally about 10% 5) Because of the relationship between the sulfur content of sintering raw materials, the SO2 concentration of flue gas changes greatly with the change of proportioning ratio 6) The oxygen content of sintering flue gas is high, about 10% - 15% 7) It contains corrosive gas. Such as: hydrogen chloride (HCl), sulfur oxides (SOx), nitrogen oxides (NOx), hydrogen fluoride (HF), etc

Tianjin Rongcheng has three sintering machines and one large sintering machine of 230 square meters under construction; 1.5 million tons grate rotary kiln oxidation pellet proction line; 4 blast furnaces; One 1 million ton rotary hearth furnace direct rection iron plant; There are three 120 ton top bottom combined blown converters, two VOD refining furnaces, one LF furnace, one double station LF furnace under construction, two four machine four strand billet casters, one six machine six strand profiled billet caster and one 1780 large slab caster; One 650 mm and one 750 mm hot rolled medium and wide strip proction line respectively; There are two sixth generation high-speed wire rod proction lines. The overall process and equipment are in line with the current national instrial policy, and some of the process and equipment have reached the domestic and international advanced level
4. Pelletizing process is a processing process in which fine grinding concentrate is made into lump materials which can meet the requirements of smelting. The process is as follows: the prepared raw materials (fine grinding concentrate or other fine grinding powder materials, additives or binders, etc.) are proportioned and mixed in a certain proportion, rolled on the pelletizing machine to make a certain size of green balls, and then dried, roasted or other methods are used to make them undergo a series of physical and chemical changes to harden and consolidate. This process is called pelletizing process, and this method is called pelletizing method. The proct is called pellet
oxidized pellets are acidic pellets, and metal pellets (Self Fusing pellets) are alkaline pellets. Metal pellets are mainly formed by adding alkaline solvents such as magnesium oxide and calcium oxide ring the formation of oxidized pellets
the main function of oxidized pellets is to adjust the pH of sinter. Metallized pellet is more suitable for blast furnace smelting than sinter, and it is a kind of potential excellent blast furnace clinker.

5. Answer quickly! Waiting to write papers!
6. Please consult our company's professionals, our Yutai company is committed to the proction and development of rotary kiln all the year round, which is your safe choice
7. Take No.8 bus to Fuhua terminal (Zhongshan bus station) and then transfer (the specific route depends on the station sign, or check the bus network first.)
8. Bus: no.307 → No.210 → no.003
walk to Nantou junior middle school station
take no.307, get off at Nantou station of urban rail transit
take No.210, get off at Western Hospital Station
take no.003, get off at Expo Center Station
take the reverse route on the return journey
no.003 → No.210 → no.307
if you want to be fast, you'd better go to Nantou station, take the urban rail to Zhongshan North Station, and then take bus 030 to the South Gate of Expo Center!!!

9.
bus line: no.003, about 6.6km in the whole journey
1. Walk about 860m from Shiqi District to Liantang Road Station
2. Take no.003, pass 10 stops and arrive at Expo Center station
