在中国的近三四年的时间里，为提升京津冀及周边地区大气污染防治，部分地区的相关环保部门根据环保政策对区域性的铸造企业进行提升改造，对个别地区（例如居住用地、高新企业用地等）直接将铸造产业列入退出产业名单；而对于铸造企业较为集中的区域则根据环保政策以及中国铸造协会提出的要求进行批次的立项整改，部分在规定期限内无响应环保要求不立项上报的铸造企业则将视为退出，通过整改验收后的企业则可以继续生产，在冬季需根据当地的天气预警实施错峰生产。

In the past three or four years in China, in order to improve the prevention and control of air pollution in Beijing, Tianjin, Hebei and surrounding areas, the relevant environmental protection departments in some regions have upgraded and transformed the regional foundry enterprises according to the environmental protection policies, and directly listed the foundry industry in some regions (such as residential land, high-tech enterprise land, etc.) as the industries to be withdrawn from the list; while for the regions with more concentrated Foundry Enterprises According to the environmental protection policy and the requirements put forward by China Foundry Association, some foundry enterprises that do not respond to the environmental protection requirements within the specified period and do not report the project will be considered as quitting. After the rectification and acceptance, the enterprises can continue to produce. In winter, they need to implement peak shifting production according to the local weather warning.

目前国内主要集中整改并且有具体指标的区域主要有河北泊头，献县，石家庄等以及山东莱州，潍坊；大部分地区（例如河南许昌，长葛，林州等）环保政策还相对不太明确，对于铸造企业（翻砂铸造）整改具体要求有以下几点：

At present, the main areas with centralized rectification and specific indicators in China are Botou, Xianxian, Shijiazhuang, Laizhou and Weifang in Shandong Province; most areas (such as Xuchang, Changge and Linzhou in Henan Province) have relatively unclear environmental protection policies, and the specific requirements for rectification of foundry enterprises (sand casting) are as follows:

首先对铸造企业将目前的基本情况——厂区面积、生产规模、生产工艺以及当前的生产装备上报，根据环保指标对自身企业做一个详细的整改方案，例如熔炼设备需采用钢壳电炉，炉顶需加装吸尘罩，能达到百分之九十的无泄露收集，外部加装布袋除尘器等确保粉尘无外漏，并且粉尘颗粒物排放浓度小于15mg/m2；

First of all, the foundry enterprise shall report the current basic situation - plant area, production scale, production process and current production equipment, and make a detailed rectification plan for its own enterprise according to the environmental protection index. For example, the smelting equipment shall adopt the steel shell electric furnace, the furnace top shall be equipped with dust absorption hood, which can achieve 90% leakage free collection, and the exterior shall be equipped with bag filter to ensure the powder There is no leakage of dust, and the emission concentration of dust particles is less than 15mg / m2;

翻砂造型将淘汰落后的人工或半自动翻砂造型，需配备相关的造型设备及造型线，浇注线，冷却线等，保证生产过程中砂不落地，浇注线和冷却线在定点浇注端则需采用侧吸除尘或者全封闭式除尘罩，气体经过除尘，布袋处理后在进入UV光氧进行二次处理，保证粉尘颗粒物排放浓度小于15mg/m2，岗位颗粒物体浓度粉尘颗粒物排放浓度小于5mg/m2；确保封闭环节严密无粉尘溢出；在生产线尾部的落砂环节同样需采用封闭式除尘；

The backward manual or semi-automatic sanding molding will be eliminated in the sanding molding. Relevant molding equipment and molding line, pouring line, cooling line, etc. shall be equipped to ensure that the sand does not fall on the ground during the production process. The pouring line and cooling line at the fixed pouring end shall adopt side suction dust removal or fully enclosed dust removal cover. The gas shall be subject to dust removal and bag treatment before entering the UV light oxygen for secondary treatment to ensure the powder The emission concentration of dust particles is less than 15mg / m2, and the emission concentration of post particles is less than 5mg / m2; ensure that the closed link is tight without dust overflow; the sand falling link at the end of the production line also needs to adopt closed dedusting;

砂处理环节则需根据厂房设计安装砂处理生产线，自动混砂加砂自动输送，为造型设备提供造型用砂，筛分环节及混砂环节也需加装布袋除尘设备对旧砂除尘等，确保砂不落地以及无粉尘颗粒溢出，粉尘颗粒物排放浓度小于15mg/m2；

In the sand treatment process, the sand treatment production line shall be installed according to the plant design, and the automatic sand mixing and automatic conveying shall be carried out to provide molding sand for the molding equipment. In the screening process and sand mixing process, bag type dust removal equipment shall also be installed to remove dust from the used sand, so as to ensure that the sand does not fall on the ground and no dust particles overflow, and the emission concentration of dust particles is less than 15mg / m2;

清理抛凡环节同样采用布袋除尘，确保无粉尘溢出，同时加装隔音以及除尘器加装消音器、减震垫等减少噪音，确保厂界噪音间不大于80分贝；

Bag type dust removal is also used in cleaning and throwing process to ensure no dust spillage. Sound insulation and silencer and damping pad are installed in the dust remover to reduce noise and ensure that the noise level within the plant boundary is not more than 80 dB;

对于厂区的配套设施要求，例如：

消防设施——车间指定位置需放置灭火器，车间通道地面标出安全出口字样，车间设置烟雾报警器、逃生指示牌、报警设施等，按照（GB50016-2014）建筑防火设计规范；

Requirements for supporting facilities in the plant area, such as:

Fire fighting facilities: fire extinguishers shall be placed at the designated position of the workshop, and the word "emergency exit" shall be marked on the floor of the workshop passage. Smoke alarms, escape signs, alarm facilities, etc. shall be set in the workshop according to the code for fire protection design of buildings (gb50016-2014);

安全设施：车间设置安全指示牌，配套放置安全用具等安全用品并加强管理；

Safety facilities: safety signs shall be set up in the workshop, safety appliances and other safety supplies shall be placed and management shall be strengthened;

卫生设施：设置工业垃圾和生活垃圾的固定存放点，定时定期进行外运处理，设定专人进行厂内的各区域环境卫生维护，使厂房干净整洁；

Sanitary facilities: set up fixed storage points for industrial waste and domestic waste, regularly carry out outbound treatment, and assign special personnel to carry out environmental health maintenance in each area of the plant, so as to make the plant clean and tidy;

对于企业管理的要求主要如下：

厂区内外环境，厂区全部做硬化，道路两侧进行绿化等，设置分划好公共活动区，停放区等；实行5S管理理念：例如成品的合理转运、存储、摆放、出入库等严格按照规定流程进行规范管理，定期检测，公辅设施专人维护管理，明确化，规范话；

The requirements for enterprise management are as follows:

The internal and external environment of the plant area shall be hardened, both sides of the road shall be afforested, and the public activity area and parking area shall be set up and divided; the 5S management concept shall be implemented: for example, the reasonable transfer, storage, placement and warehousing of finished products shall be strictly in accordance with the specified process for standardized management, regular inspection, maintenance and management of public and auxiliary facilities by specially assigned personnel, which shall be clear and standardized;
